Consider the following reaction
4 HCl (g) + O2 (g) à 2 H2O (g) + 2 Cl2 (g)
What is the equilibrium composition of the system when the system initially contains only HCl and O2 in molar ratio of 5. The reaction temperature is 298 K and Pressure is 2 bar.
Discuss qualitatively the effect of change in equilibrium constant when pressure is changed from 2 bar to 1 bar.
