Question

Of the following, ________ will lower the activation energy for a reaction. Select one: a. removing products as the reaction proceeds b. increasing the pressure c. adding a catalyst for the reaction d. raising the temperature of the reaction e. increasing the concentrations of reactants

Answer 1

Answer:

The correct answer is c. adding a catalyst for the reaction

Explanation:

The function of a catalyst in a chemical reactionis to increase the rate of reaction by decreasing the required activation energy which is clearly illustrated on energy diagrams. It is not consumed in the reaction and can be reused repeatedly,as such, only small quantities of catalysts are required in the reaction. Catalyst provide a separate route for a chemical reaction to proceed at a lower activation energy than an uncatalysed reaction

The process of speeding up a chemicals reaction by the addition of a catalyst is known as catalysis
