The equilibrium concentrations for the reaction Cl₂ (g)+ PCl₃ (g)⇔ PCl₅ (g)at 300 K are [Cl₂] = 0.75 M, [PCl₃] = 0.45 M, and [PCl₅] = 0.73 M. Based on the calculated value of the equilibrium constant, the reaction is ________.

Question

Quizplus · Accepted Answer

To determine whether the reaction is favorable or not, we need to compare the Q (reaction quotient) with K (equilibrium constant). If QK, the reaction will proceed in the reverse direction, which means the reactants are favored. Here, the equilibrium constant can be calculated using the formula: Kc = [PCl₅]/([Cl₂][PCl₃]) = 0.73/(0.75x0.45) = 1.62 Since the value of Kc is greater than 1, it indicates that the products are favored over reactants in this reaction. Thus, the answer is A, favorable.
