The following diagram represents the equilibrium state for the reaction: A2 (g) + 2 B (g) ↔ 2 AB (g) a) Assuming the volume is 1 dm3 , calculate the equilibrium constant for the reaction. b) If the volume of the equilibrium mixture is decreased, will the number of AB molecules increase or decrease? Say why. c) Below are two diagrams showing a microscopic representation of the reaction: X2 + Y ↔ X + XY The diagrams represent the same reaction at two different temperatures: 300 K and 500 K. Is the reaction exothermic or endothermic? Say why.
