The adsorption of a gas at the boiling point of the gas follows the isotherm shown in the figure. Identify the correct thermodynamic properties at point C .
Options
- AH=T S, G=0
- BH>T S, G=+ ve
- CH < T S, G=-v e
- DH=T S= G=0
Correct answer
A. H=T S, G=0
Step-by-step solution
Amount of gas adsorbed remains constant at point C irrespective of increase in pressure. So, the system is in equilibrium G=0 As we know, G= H-T S H=T S .
