For a gaseous homogeneous reaction at equilibrium, number of moles of

1.	For a gaseous homogeneous reaction at equilibrium, number of moles of products are greater than the number of moles of reactants. Is KC is larger or smaller than KP?
Answer» 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 ∆n_g = + ve n_P > n_R ∆n_g = + ve If ∆n_g is ve, K_p value is greater than K_C K_P = K_C . (RT)^+ve K_P > K_C Example: PCl₅ PCl₃_(g) + Cl₂_(g) 2 – 1 = 1 K_P = K_C (RT)¹ K_P > K_C

Answer»

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 ∆n_g = + ve

n_P > n_R

∆n_g = + ve

If ∆n_g is ve, K_p value is greater than K_C

K_P = K_C . (RT)^+ve

K_P > K_C

Example: PCl₅ PCl₃_(g) + Cl₂_(g)

2 – 1 = 1

K_P = K_C (RT)¹

K_P > K_C
