Reaction Rate, Temperature & the Arrhenius Equation

The rate of a particular reaction triples when the temprature is increased from 25C to 35C. Calculate the activation energy for this reaction.

Also i just need to clearify the concept of Arrhenius Equation. What happened to Rate Constant(k) and the rate of reaction if:
a. there is a decrease in temperature
b. an increase in activation energy of the forward and reverse reactions. and the last is if there is an increase in both activation energy and temperature. I want to know the effect of each on Rate constant and rate of reaction

Solution Summary

The solution attaches a .doc file including calculations for finding the activation energy with temperature increase as well as an explanation of the Arrhenius Equation.
