The rate constant for decomposition of compound X was determined to be 1.0x10^-4 s-1 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 1.0-4. 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
You should use the Arrhenius equation. Substitute the numbers and solve Ea.
