WebThe equilibrium constant for a reaction can be used to predict the behavior of mixtures containing its reactants and/or products. As demonstrated by the sulfur dioxide oxidation … WebThe effect of temperature on equilibrium If the temperature of a reaction mixture is changed, the equilibrium will shift to minimise that change. If the temperature is increased the equilibrium will shift to favour the reaction which will reduce the temperature. The endothermic reaction is favoured.

WebCase 1: The larger value of the equilibrium constant (>10 3) shows that forward reaction is favored i.e. the concentration of products is much larger than that of the reactants at equilibrium. For Example: H 2 (g) + Br 2 (g)⇌ … WebThe total pressure of the gases at equilibrium with a catalyst present would be equal to the total pressure of the gases without a catalyst. Although a catalyst would cause the system to reach the same equilibrium state more quickly, it would not affect the extent of the reaction, which is determined by the value of the equilibrium constant,K p
