Question

A particular first-order reaction has a rate constant of 1.35x10^2 at 20 degrees C. What is the magnitude of k at 75 degrees C if Ea =85.6Kj/mol?;(I'm trying to solve it by finding A with k=Ae^-Ea/RT using the first temperature, then finding k for the second temperature using the value previously derived for A. Am I doing this correctly? My numbers are always off. Could you show me the steps?);Additional Requirements;Level of Detail: Show all work;Other Requirements: I'm very unsure about the math, so if you could write out *all* the steps that would be helpful.
