At 1500 K, the process

I 2 ( g ) 2 I ( g ) 10 atm 10 atm

is not spontaneous. However, the process

I 2 ( g ) 2 I ( g ) 0.10 atm 0.10 atm

is spontaneous at 1500 K. Explain.

Interpretation Introduction

Interpretation: A chemical process that is not spontaneous at 1500K at a pressure of 10atm is given to be spontaneous at a pressure value of 0.10atm . This phenomenon is to be explained.

Concept introduction: The value of ΔG° for a spontaneous reaction is negative (less than one).



The value of entropy of a gas increases with the decrease in pressure.

In the given case, when the pressure is decreased, the entropy increases.

The formula to calculate the standard free energy change at temperatures above 25°C is,
