C6H12O6(aq)+H2(g)---C6H14O6(aq)

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

ΔH

ΔH

ΔHΔH


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
