Hello,

I am having a hard time solving this question about the TST:

If the following gas-phase radical recombination reaction

.CH

_{3}+.CH

_{3} C

_{2}H

_{6}has a rate constant of 0.22 L mole

^{-1} min

^{-1} at 600

^{o}C. According to transition state theory, the reaction's rate at 900

^{o}C is:

a) 0.22 L mole

^{-1} min

^{-1}b) 0.37 L mole

^{-1} min

^{-1}c) 0.33 L mole

^{-1} min

^{-1}d) 0.30 L mole

^{-1} min

^{-1}e) 0.44 L mole

^{-1} min

^{-1}---------------------------------

I thought of using the equation:

k=(k

_{B}T/h)e

^{G/RT}for the first T and get delta G at transition state, and then calculate the second k at 900 using the same G. But I think it is wrong since the G is changing with changing the temperature, right?
