Submitted by zray13fu on Sat, 08/03/2013 - 22:07


which of the following are affected by a catalyst 



Rate of the reverse reaction


Spontaneity of the reaction


delta H


delta S


delta G


The equilibrium constant


Time required to reach equilibrium




Rate of the reverse reaction: catalyst changes the rate of reaction ,it increases the rate of reaction in both forward and reverse direction.

Spontaneity of the reaction ; no effect

delta H; no effect

delta S; no effect

delta G ; no effect

The equilibrium constant: is not changed if you add (or change) a catalyst.

Time required to reach equilibrium; no effect
