An increase in temperature favours an endothermic reaction over an exothermic one as an endothermic reaction takes in the energy from the higher temperature more easily than the exothermic reaction gives out even more energy to the surroundings. Therefore an increase in temperature increases the level of completion and viability of an endothermic reaction, and the opposite for an exothermic reaction.
An increase in pressure favours any reaction that forms fewer molecules from more molecules. It does not necessarily favour an exothermic or an endothermic reaction as it depends on the number of molecules on either side of the reaction. An endothermic reaction involves the breaking of bonds to a greater extent than an exothermic reaction, so an increase in pressure would, in a lot of cases, favour the exothermic reaction more than the endothermic reaction.
For an exothermic reaction, increasing temperature typically decreases the rate of the reaction due to a shift in the equilibrium favoring the reactants. In contrast, for an endothermic reaction, increasing temperature usually increases the rate of the reaction as it helps provide the necessary energy required by the reactants. Pressure changes typically have a minor effect on the rate of both exothermic and endothermic reactions, as they primarily affect the equilibrium position rather than the reaction rate.

Is evaporating always an exothermic reaction?
No, evaporating is not always an exothermic reaction. Evaporation is the process of a liquid turning into a gas, and whether it is exothermic or endothermic depends on the specific conditions such as temperature and pressure.
What is the difference of the endothermic and exothermic change?
Endothermic change absorbs heat from the surroundings, resulting in a decrease in temperature. Exothermic change releases heat to the surroundings, leading to an increase in temperature.
How are exothermic and endothermic reactions different?
Exothermic reactions release heat to the surroundings, causing the surroundings to increase in temperature. Endothermic reactions absorb heat from the surroundings, causing the surroundings to decrease in temperature.
A neutralization reaction was carried out in a calorimeter The temperature of the solution rose from 20.0 C to 25.6 C Is this reaction endothermic or exothermic?
This reaction is exothermic because the temperature of the solution rose. In an exothermic reaction, heat is released to the surroundings, causing an increase in temperature.
What is the opposite of exothermic?
The opposite of exothermic is endothermic. Exothermic reactions are those which give off energy in the form of heat. Endothermic reactions require energy.
Is evaporating always an exothermic reaction?
No, evaporating is not always an exothermic reaction. Evaporation is the process of a liquid turning into a gas, and whether it is exothermic or endothermic depends on the specific conditions such as temperature and pressure.
When the temperature changes cause of a reaction is it exothermic or endothermic?
If the temperature increases during a reaction, it is exothermic. This means that heat is being released into the surroundings. If the temperature decreases during a reaction, it is endothermic, meaning heat is being absorbed from the surroundings.
How does an exothermic reaction differ from n endothermic reaction?
An exothermic reaction releases heat to its surroundings, resulting in a temperature increase. In contrast, an endothermic reaction absorbs heat from its surroundings, causing a decrease in temperature.
How would you know if a reaction was endothermic or exothermic?
You can determine if a reaction is endothermic or exothermic by observing whether heat is absorbed or released during the reaction. If heat is absorbed, the reaction is endothermic. If heat is released, the reaction is exothermic. You can also measure the temperature change of the surroundings to confirm the type of reaction.
What is the difference of the endothermic and exothermic change?
Endothermic change absorbs heat from the surroundings, resulting in a decrease in temperature. Exothermic change releases heat to the surroundings, leading to an increase in temperature.
How can you tell the difference between an endothermic and exothermic reaction?
You can generally tell by changes in temperature, whether you have an exothermic reaction which produces heat, or an endothermic reaction which consumes heat.
How are exothermic and endothermic reactions different?
Exothermic reactions release heat to the surroundings, causing the surroundings to increase in temperature. Endothermic reactions absorb heat from the surroundings, causing the surroundings to decrease in temperature.

This reaction is exothermic because the temperature of the solution rose. In an exothermic reaction, heat is released to the surroundings, causing an increase in temperature.
What is the type of heat reaction which occurs when heat is given off by the reaction?
An exothermic reaction is one in which heat is released or given off as a product of the reaction. This is often associated with a rise in temperature in the surrounding environment.
What two types of energy change can occur in a chemical reation?
Two types of energy change that can occur in a chemical reaction are endothermic or exothermic. An exothermic reaction causes an increase in temperature and an endothermic reaction causes a decrease in temperature.
What is the opposite of exothermic?
The opposite of exothermic is endothermic. Exothermic reactions are those which give off energy in the form of heat. Endothermic reactions require energy.
If the temperature after a reaction is higher is the reaction endothermic or exothermic?
If the temperature rises, the reaction is EXOTHERMIC where the system (reaction) is giving off heat to the surroundings (water, beaker, test tube, etc.).
