Question

Consider the reaction X2Y(g) X2(g) + 1 Y2(g) The equation representing correct relationship between the degree of dissociation (x) of X2Y(g) with its equilibrium constant Kp is_______. Assume x to be very very small. (A) x = 3 p p K (B) x = 3 p Kp (C) x = 3 p Kp (D) x = 3 p Kp

Answer: B

💡 Solution & Explanation

X2Y (g) X2(g) + 1 Y2 (g) t = 0 P0 O O P0 – X X x P0 – P0 P0  P0  PT = P0 + P0  = P0 (1 + ) KP =          – P P P 2 0 = P 3 1 0  ;  = 3 2 p P K
