1.	In an equilibrium A+BhArrC+D,A and B are mixed in a vessel at temperature T.The initial concentration of A was twice the initial concentration of B. After the attainment of equilibrium, concentration of C was thrice concentration of B, calculate K_(c).
Answer» `K_c=1.8` `[A]_(eqn)=[d]_(eqn) xx 1.66` `K_c=2.8` `[A]_(eqn) = [C]_(eqn) xx 2.5` Solution : given `[c]_(eqn)=3[B]_(eqn)` `X=3(a-x), x=(3A)/(4)` `[A]_(eqn)=(5a)/(4), [B]_(eqn)=(a)/(4), [C]_(eqn)=(3a)/(4), [D]_(eqn)=(3a)/(4)`
