A mixture of 1 mole of \({\mathrm{H}}_{2}\mathrm{O}\) and 1 mole of CO is taken in a 10 litre container and heated to 725 K. At equilibrium 40% of water by mass reacts with carbon monoxide according to the equation :

\(\mathrm{CO}(\mathrm{g})+{\mathrm{H}}_{2}\mathrm{O}(\mathrm{g})\to {\mathrm{CO}}_{2}(\mathrm{g})+{\mathrm{H}}_{2}(\mathrm{g})\)

The value of \({\mathrm{K}}_{\mathrm{C}}\times {10}^{2}\) for the reaction is_______.

(K_C - Equilibrium constant) (Nearest integer)
