As we learnt in 

Arrhenius Equation -

Arrhenius gave the quantitative dependence of rate constant on temperature by the Arrhenius equation.

- wherein

k = A e^{-E_{a}/RT}

In k=InA-\frac{E_{a}}{RT}

k = Rate constant

 

 k=A\times e^{\frac{-E_{a}}{RT}}

Where A is Pre-exponential factor

K=Rate constant

R=Gas constant

T=Absolute temprerature

E_{a}=Activation Energy


Option 1)

k is equilibrium constant

Incorrect Option

Option 2)

A  is adsorption factor

Incorrect Option

Option 3)

E_{a} is energy of activation

Correct Option

Option 4)

R  is Rydberg constant.

Incorrect Option
