D. Activation energy does not change with an increase of temperature. The rate constant does, but the activation energy does not.

All of the others are false (activation energy decreases with the addition of a catayst, activation energy does not change with a decrease in temperature, and it does not change if the solution is stirred vigorously).

Is there a none of the above option?

Reaction rate increases with a decrease in activation energy correct?

So if a catalyst should decrease the activation energy cuz it increases the rate of reaction (so its not A).

A temperature increase would increase the rate of reaction and thus lower the activation energy. ( cant be B or D)

Stirring a solution vigorously should also increase the rate of reaction and decrease the activation energy (so cant be C either)
