Question

The fraction of molecules having energy equal to or greater than activation energy is ______.

Options

• A

• `e^(−E_a//RT)`

• K

• `A e^(−E_a//RT)`

Answer 1

The fraction of molecules having energy equal to or greater than activation energy is `bbunderline(e^(−E_a//RT))`.

Explanation:

As the temperature of a substance rises, the molecules collide with energy exceeding the activation energy. In the Arrhenius equation, the term `e^(−E_a//RT)` represents molecules possessing energy equal to or exceeding the activation energy.
