For the reaction
`H_(2)(g)+CO(g)hArrCO(g)+H_(2)O(g),` if the initial concentration of`[H_(2)]=[CO_(2)]`and x moles /litres of hydrogen is consummed at equilibrium , the correct expression of `K_(p)` is :

For the reaction H_(2)(g)+CO_(2) (g)hArrCO(g)+H_(2)O(g), if the initial concentration of [H_(2)]=[CO_(2)] and x moles /litres of hydrogen is consumed at equilibrium , the correct expression of K_(p) is :

For the reaction, H_(2)(g)+CO_(2)(g) hArr CO(g)+H_(2)O(g) , if the initial concentration of [H_(2)]=[CO_(2)] and x mol L^(1) of H_(2) is consumed at equilibrium, the correct expression of K_(p) is:

For the reaction H_(2)(g) + CO_(2)(g) rarr CO(g) + H_(2)O(g) , If the initial concentration of [H_(2)] = [CO_(2)] = 1 "and" x mol//L of hydrogen is consumed at equilibrium, the correct expression of Kp is :

At a given temperature, Ke is 4 for the reaction H_(2(g)) + CO_(2(g)) hArr H_(2)O_((g)) + CO_((g)) . Initially 0.6 moles each of H_(2) and CO_(2) are taken in 1lit flask. The equilibrium concentration of H_(2) O_((g)) is
