1.	In the equilibrium, 2A(g) hArr 2B(g)+ C_2(g) the equilibrium concentrations of A, B and C_2 at 400 K are 1 xx 10^(-4) M,2.0 xx 10^(-3) M, 1.5 xx 10^(-4)Mrespectively. The value of K_C for the equilibrium at 400 K is ………………… .
Answer» 0.06 0.09 0.62 `3 XX 10^(-2)` Solution :`[A] = 1xx 10^(-4) M, [B] = 2XX 10^(-3) M, [C] = 1.5 xx 10^(-4) M` `2A(g) hArr 2B(g) + C_2(g)` `K_C = ([B]^2[C_2])/([A]^2)=((2xx 10^(-3))^2(1.5 xx 10^(-4)))/((1xx 10^(-4))^2)` `= 6.0 xx 10^(-2) = 0.06`
