Title: Chemical Kinetics--catalyst word problem
Post by: hanuma94 on January 18, 2012, 10:11:19 PM
The activation energy of an uncatalyzed reaction is 95 kJ/mol. The addition of a catalyst lowers the activation energy to 55 kJ/mol. Assuming that the collision factor remains the same, by what factor will the catalyst increase the rate of the reaction at a)25 C and b) 125 C?

Thank you!

Okay
use the Clausius Clapeyron equation  to take the ratio of  K at 25 deg c and 125 deg C with catalyst and without catalyst
