When a catalyst is present is more or less activation energy needed to start a chemical reaction?
When a catalyst is present, less activation energy is needed to start a chemical reaction. This is because the catalyst provides an alternative pathway for the reaction to occur, allowing it to proceed more readily. The catalyst achieves this by lowering the activation energy barrier for the reaction.
What is the difference between the predicted and actual yield in a chemical reaction?
The actual yield of a reaction product is always less than the yield from the chemical equation. This is because of error.
What effect does a catalyst have?
A catalyst speeds up a chemical reaction by lowering the activation energy required for the reaction to occur. It does so by providing an alternative reaction pathway that requires less energy to initiate the reaction. The catalyst itself remains unchanged at the end of the reaction and can be used over and over again.
What is a type of chemical reaction where the energy of the products is less than the energy of the reactants?
An exothermic reaction is a type of chemical reaction where the energy of the products is less than the energy of the reactants. This means that energy is released during the reaction in the form of heat or light. Examples include combustion reactions and many neutralization reactions.
If the amount of oxygen reaching the log is reduced what happens to the rate of this chemical reaction?
The rate of the chemical reaction will decrease because oxygen is one of the reactants required for the reaction to occur. With less oxygen available, the reaction will proceed at a slower pace.
