Problem

For gaseous reaction A+B⇌CA + B \rightleftharpoons C , the equilibrium concentration of A and B at a temperature are 15 mol litre−1litre^{-1} . When volume is doubled the reaction had equilibrium concentration of A as 10 mol litre−1litre^{-1} . Calculate : (a) KCK_C (b) concentration of C in original equilibrium.
