Question

When a catalyst is involved in the collision between the reactant molecules, more energy is required.

(a) True

(b) False

I had been asked this question by my school teacher while I was bunking the class.

My doubt is from Collision Theory of Chemical Reactions topic in portion Chemical Kinetics of Chemistry – Class 12

Answer 1

Right answer is (b) False

To explain I would say: When a catalyst is involved in a collision between the reactant molecules, less energy is required for the chemical reaction to take place. Catalyst brings down the activation energy of the overall chemical reactions and the reaction takes place at a lower energy state.
