As we learned in concept

Effect of Temperature and Activation Energy on rate constant -

E_{a}= 0                k\neq f(T)

E_{a}< 0                k decreases with the increase in T

 

 

E_{a}> 0                 k increases with increase in T

E_{a} = Activation Energy

T = Temperature

 k = Rate constant

- wherein

Arrhenius equation is given by 

 

k=Ae^-{\frac{Ea}{Rt}}

\ln k= \ln A- \frac{Ea}{RT}

\ln k= \ln A-\frac{Ea}{R}(\frac{1}{T})

The graph of the above equaion can be drawn as follows:
