Question

A substance with a high activation energy is expected to have a _____ reaction rate.

Answer 1

Answer:

A substance with a high activation energy is expected to have a slow reaction rate.

Answer 2

Since we know that the activation energy of a particular reaction determines the rate at which it will proceed. The higher the activation energy, the slower the chemical reaction will be.

Hence, a substance with a high activation energy is expected to have a slow reaction rate.
