One mole of  and one mole of  are taken in 10 L vessel and heated to 725 K. At equilibrium, 40% of water (by mass) reacts with  according to the equation.

Calculate the equilibrium constant for the reaction.

Solution: The number of moles of water that have reacted are .

Moles of water unreacted are mol.

0.4 moles of water reacts with 0.4 mole of CO to form 0.4 moles of hydrogen and 0.4 moles of carbon dioxide.

The equilibrium molar concentrations are:

The equilibrium constant is .
