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
