The rate constant for decomposition of compound X was determined to be 1.0x10^4 s1 at 298 K and 1.0x10^2 at 365 K. The activation energy for reaction is:
I don't know if this is correct 8.314 x 10^3 x 298x365 divided by 365  298 x In 1.0 x10^2 divided by 1.04. This gives a different answer.
What equation is used and all the maths steps as I really need help with this problem.
The answer should be 6.2 x 10^4 J mol 1
Thank you

You should use the Arrhenius equation. Substitute the numbers and solve E_{a}.
