The reaction mechanism assumption that is most important for the explanation of the influence of catalysts on reaction rates is to be stated. The explanation for the corresponding answer is to be stated.
Concept introduction:
Rate of a reaction is defined as the speed by which the reaction is proceeding. The rate of reaction depends on several factors such as concentration of reactant and temperature. The rate of the reaction is represented as,

- . Account for the increase in reaction rate brought about by a catalyst.arrow_forwardHow is it possible for a catalyst to give products from a reaction mixture that are different from those obtained when no catalyst or a different catalyst is used? Give an example.arrow_forwarda What happens to a reaction rate as temperature drops? Give two explanations for the change. State which one is more important and explain why. b How does a catalyst affect reaction rates? c Compare reaction rates when a given reactant concentration is high with the rate when the concentration is low. Explain the difference.arrow_forward
- use the kineticmolecular theory to explain why an increase in temperature increases reaction rate.arrow_forwardWhat is the role of the activated complex in a chemical reaction?arrow_forwardIf a textbook defined a catalyst as "a substance that increases the rate of a reaction," would that definition be adequate?arrow_forward
