Chapter 17, Problem 17.148MP

Interpretation Introduction

(d) To determine:

the effect of catalyst on $\Delta H^0$

Interpretation Introduction

(e) To determine:

the effect of catalyst on $\Delta S^0$

Similar like H, S is also a property of the products and reactants only, it doesn’t change even if you add catalyst. Therefore, $\Delta S^0$ will not change for addition of catalyst.

(f)To determine the effect of catalyst on $\Delta G^0$

Interpretation Introduction

Equilibrium is defined as the point when both forward and reverse reactions have the same rate. Since both forward and reverse reaction are equally affected by the catalyst, hence the equilibrium constant is not affected by catalyst.

(h) To determine the effect of catalyst on time required to reach equilibrium
