Question
In respect of the equation $$k = A{e^{ - \,\frac{{{E_a}}}{{RT}}}}$$ in chemical kinetics, which one of the following statements is correct ?
A.
$$A$$ is adsorption factor
B.
$${E_a}$$ is energy of activation
C.
$$R$$ is Rydberg’s constant
D.
$$k$$ is equilibrium constant
Answer :
$${E_a}$$ is energy of activation
Solution :
In equation $$k = A{e^{ - \,\frac{{{E_a}}}{{RT}}}};A = $$ Frequency factor
$$k =$$ velocity constant, $$R =$$ gas constant and
$${E_a} = $$ energy of activation
