The rate constant of a reaction at temperature $200 K$ is 10 times less than the rate constant at $400 K$ . What is the activation energy of the reaction?

Options:

Answer:

Solution:

At $T_{1} = 200 K$ , if $k_{1} = k$ then at $T_{2} = 400 K, k_{2} = 10 k$ $lo g \frac{10 k}{k} = \frac{E _{a}}{2.303 R} (\frac{400 - 200}{400 \times 200}) E_{a} = 921.2 R$
