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 (

{E_a}

) of the reaction?

View answer and explanation

Correct option: B

921.2\;R

Option B (

921.2\;R

) is correct because it is the activation energy calculated using the Arrhenius equation, given the rate constants at two different temperatures.
