The rate constant (k) of a reaction is measured at different temperature (T), and the data are plotted in the given figure. the activation energy of the reaction in kJmol-1 is : (R is gas constant)

Options:

Answer:
D
Solution:

k=Ae-Ea/RT
In k=InA−EaR1T

In k=InA−EaR×103103T

Slope of graph 

=−EaR×103=−105

Ea=2R×103J

Ea=2R×kJ
