1.	For a gaseous homogeneous reaction at equilibrium, number of moles of products are greater than the number of moles of reactants. Is K_C is larger or smaller than K_P ?
Answer» Solution :For a homogeneous reaction at equilibrium, number of MOLES of products `(n_p)` are GREATER than the number of moles of reactants `(n_R)`, then `Deltan_g = + ve` `n_P gt n_R` `:. Deltan_g = +ve ` If `Deltan_g` is + ve, `K_P` VALUE is greater then `K_C` `K_P = K_C. (RT)^(+ve)` `:.K_P gt K_C` Example :`PCl_5 (g) HARR PCl_3(g) + Cl_2(g)` ` 2 - 1 = 1` `:.K_P = K_C(RT)^1` `K_P gt K_C`
