If I could get some help, I would be so grateful to you!  I am struggling.  Chemistry is not a strong point for me, unfortunately.  

Problem 14.95
The activation energy of an uncatalyzed reaction is 91kJ/mol . The addition of a catalyst lowers the activation energy to 46kJ/mol .

Part A

Express your answer using two significant figures.

Part B
Assuming that the collision factor remains the same, by what factor will the catalyst increase the rate of the reaction at 115?C?
