For a chemical reaction system, Q and K are the reaction quotient and equilibrium constant, respectively. Identify the true statement(s).1. If Q is equal to K, the system is at equilibrium.2. If Q is greater than K, the ratio of initial concentrations of products to initial concentration of reactants is small.3. If Q is less than K, the ratio of initial concentration of products to initial concentration of reactants is large.

Quizplus · Accepted Answer

1. This statement is true. When the reaction quotient, Q, equals the equilibrium constant, K, the system is at equilibrium. 
2. This statement is false. If Q is greater than K, it means that there is an excess of products, indicating that the ratio of initial concentrations of products to initial concentration of reactants is larger. 
3. This statement is false. If Q is less than K, it means that there is a deficiency of products, indicating that the ratio of initial concentration of products to initial concentration of reactants is smaller.
