Question

What will be the fraction of molecules having energy equal to or greater than activation energy, Ea?
(a) K
(b) A
(c) Ae-Ea/Rt
(d) e-Ea/Rt

Answer 1

Question : What will be the fraction of molecules having energy equal to or greater than activation energy, $E_a$ ?

(a) K

(b) A

(c) $Ae^{-\frac{E_a}{RT}}$

(d) $e^{-\frac{E_a}{RT}}$

solution : according to Arrhenius equation,

$K=Ae^{-\frac{E_a}{RT}}$

where $e^{-\frac{E_a}{RT}}$ represents fraction of molecules having energy equal to or greater than activation energy, $E_a$.

Therefore the correct option is (D) $e^{-\frac{E_a}{RT}}$.
