Chemical Equilibrium

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


\(\mathrm{CO}(\mathrm{g})+\mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \rightleftharpoons \mathrm{CO}_{2}(\mathrm{~g})+\mathrm{H}_{2}(\mathrm{~g})\).


The equilibrium constant \(\mathrm{K}_{\mathrm{c}} \times 10^{2}\) for the reaction is ____________. (Nearest integer)
