Question

Which letter corresponds to the activation energy of the reaction after the addition of a catalyst?

• A. A
• B. B
• C. C
• D. D
• E. E

Answer 1

Answer: (E)

E

E is the correct option. Catalyst decreases the activation energy requirement and increases the rate of the chemical reaction. Here A is the activation energy required for the reaction to occur when there is no catalyst. And E is the activation energy required for the reaction to occur in presence of a catalyst.
