Question

The activation energy of an uncatalyzed reaction is 91kJ/mol . The addition of a catalyst lowers the activation energy to  46kJ/mol .
Part A Assuming that the collision factor remains the same, by what factor will the catalyst increase the rate of the reaction at 33?C?

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?

Explanation / Answer

ln(k2/k1)=E1/E2

or ln(x)=(91+46)/(91)

or x=4.5 times

a)4.5 times

b)4.5 times
