Homework Help: chemistry

Posted by kathryn on Monday, March 5, 2012 at 2:41pm.

I have two questions that I really don't understand.

The first one is: A reaction proceeds with delta H=-10kJ/mol. The energy of activation of the uncatalyzed reaction is 150kJ/mol, whereas it is 100kJ/mol for the uncatalyzed reaction. How many times faster is the catalyzed reaction than the uncatalyzed reaction at 25 degrees C.

The second question is: At 30 degrees C, a reaction produces product at the rate of 0.613 mol/Lxh. If the activation energy is 88 kJ/mol, what will the reaction rate be at 45 degrees C.

I appreciate any help, thanks!
