The value of Ke in mol/L at the same temperature is? Give the answer in terms of 10- For a chemical reaction, the equilibrium constant can be defined as the ratio between the amount of reactant and the amount of product which is used to determine chemical behaviour. At equilibrium, Rate of the forward reaction = Rate of the backward reaction i.e. r f = r b Or, kf × α × [A]a[B]b = kb × α × [C]c [D]d At 900 K, the equation constant (Kp) for the following reaction is 0.345 . 2SO2 (g) + O2 (g) -> 2SO3 (g) At equilibrium, the partial pressure of SO2 is 36.9 arm & that of O2 is 16.8 arm. The partial pressure of SO3 at equilibrium is _____ atm 88.8 At 24*C, Kp = 0.080 for the equilibrium: NH4HS (s) <-> NH3 (g) + H2S (g)This is called K p , the equilibrium constant in terms of the partial pressure. K P = P C 3 P D 4 P A P B 2 Therefore, for this particular equilibrium, the ratio of partial pressures is also a constant. Relation between KP & KC In general, the relation between KP and KC is K P = K C (RT) ΔnExplanation: The relationship between Kc and Kp is in the formula Kc = Kp ⋅ (RT)Δn The R value used is in atmospheres and the T value is in kelvins. Δn is the sum of the coefficients of products minus the sum of the coefficients of the reactants. Example aA+bB ⇔ cC+bB Δn = (c + b) − (a + b)This is called K p , the equilibrium constant in terms of the partial pressure.

In general, we use the symbol or to represent equilibrium constants. When we use the symbol , the subscript c means that all concentrations are being expressed in terms of molar concentration, or . It may be noted that Q becomes equal to equilibrium constant (K) when the reaction is at the equilibrium state.At equilibrium, Q = K = K c = K p.Thus, (a) If Q > K, the reaction will proceed in the direction of reactants (reverse reaction). (b) If Q < K, the reaction will proceed in the direction of the products (forward reaction). (c) If Q = K, the reaction mixture is already at equilibrium.The equilibrium constant, Kp, for the following reaction is 0.497 at 500 K: PCl5 (g) PCl3 (g) + Cl2 (g) Calculate the equilibrium partial pressures of all species when PCl5 (g) is introduced into an evacuated flask at a pressure of 1.46 atm at 500 K.
