Question

In a first–order reaction (A → B and rate = k [A]), tripling the concentration of A will have what effect on the reaction rate?

Answer 1

Answer:

Tripling the concentration of A will triple the reaction rate.

Explanation:

• For a first–order reaction hat has a rate law:

Rate = k[A].

• It is clear that the reaction rate is directly proportional to the concentration of A.

Rate ∝ [A].

So, Tripling the concentration of A will triple the reaction rate.
