The equilibrium constant of the reaction H2O(g)+CO(g)⇌H2(g)+CO2(g), is 0.44 at 1259 K. The value of equilibrium constant of the reactionH2(g)+CO2(g)⇌H2O(g)+CO(g)will be

# The equilibrium constant of the reaction ${\mathrm{H}}_{2}\mathrm{O}\left(\mathrm{g}\right)+\mathrm{CO}\left(\mathrm{g}\right)⇌{\mathrm{H}}_{2}\left(\mathrm{g}\right)+{\mathrm{CO}}_{2}\left(\mathrm{g}\right)$, is 0.44 at 1259 K. The value of equilibrium constant of the reaction${\mathrm{H}}_{2}\left(\mathrm{g}\right)+{\mathrm{CO}}_{2}\left(\mathrm{g}\right)⇌{\mathrm{H}}_{2}\mathrm{O}\left(\mathrm{g}\right)+\mathrm{CO}\left(\mathrm{g}\right)$will be
