Equilibrium constant `K_(c)` is expreseed as the concentration of products divided by reactants , each term raised to the stoichiometric coefficient for reaction `aA+bB hArr cC+ dD` `K_(c) = [[C]^(c)[D]^(d)]/[[A]^(a)[B]^(b)] ("unit of concentration are " mol//L)` Answer the following on the basis of above paragrah (i) Write the equilibrium constnat for the reaction `N_(2)(g) + 3H_(2)(g) hArr 2NH_(3)(g)` (ii) Write the units of equilibrium constant for the reaction `N_(2) (g) +O_(2) (g) hArr 2NO (g)` (iii) What will be the effect of catalyst on the euilibrium constant : |

Answer» `(i) K_(c) =[[NH_(3)]^(2)]/[[N_(2)][H_(2)]^(3)]` `(ii) K_(c) =((mol L^(-1))^(2))/((mol L^(-1))(mol L^(-1)))` Equilibrium constant has no units . (iii) A catalyst does not influence the reaction in a state of equilibrium . Therefore equilibrium constant has no units. |
