Question

Substance that increases the rate of a reaction without being used up?

A. Inhibitor
B.Catalyst
C.Rate Law
D.Activation Energy

Answer 1

B Catalyst

Step-by-step explanation:

catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism. Enzymes are proteins that act as catalysts in biochemical reactions.That is why B is the right answer.

Answer 2

B) Catalyst // it increases the rate of the reaction by lowering the activation energy without having itself consumed by the reaction.
