Effects of temperature and pressure on exothermic and endothermic reaction?
Wiki User
∙ 14y ago
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.

What is the difference of the endothermic and exothermic change?
An endothermic change requires heat, and an exothermic change releases heat.
How can an endothermic reaction be spontaneous at room temperature?
Exothermic, as endothermic reactions require activation energy.
What is the sign of ΔT in an endothermic reaction?
ΔH is the enthalpy of the reaction and will be positive in an endothermic reaction and negative in an exothermic reaction.ΔT designates a change in temperature. T2-T1 = ΔTOften the change in temperature will be negative for an endothermic reaction.
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.).
When the temperature changes cause of a reaction is it exothermic or endothermic?
It is exothermic
What is the difference of the endothermic and exothermic change?
An endothermic change requires heat, and an exothermic change releases heat.
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 would you know if a reaction was endothermic or exothermic?
An endothermic reaction is one in which thermal energy, or heat, is absorbed. If heat is absorbed in the reaction process, it is endothermic. By monitoring the temperature of the reactants in a reaction, an observer could identify an endothermic reaction through observation of a decrease in the temperature.
How can an endothermic reaction be spontaneous at room temperature?
Exothermic, as endothermic reactions require activation energy.
When hydrochloric acid neutralizes sodium hydroxide the temperature increases is this exothermic or endothermic?
When the temperature increases as a result of reaction, as specified here, the reaction is exothermic.
What is the sign of ΔT in an endothermic reaction?
ΔH is the enthalpy of the reaction and will be positive in an endothermic reaction and negative in an exothermic reaction.ΔT designates a change in temperature. T2-T1 = ΔTOften the change in temperature will be negative for an endothermic reaction.
When clothes are drying is it an endothermic or an exothermic reaction?
The combustion is exothermic.
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.
Formation of choloform is endothermic or exothermic reaction?
Formation of choloform is endothermic or exothermic reaction?
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.).
