A solution of 0.5 M benzaldehyde is treated with 0.5 M sodium hydroxide. If the equilibrium constant for the reaction is 1.2, what is the concentration of the benzoate ion at equilibrium?
Q1. A solution of 0.5 M benzaldehyde is treated with 0.5 M sodium hydroxide. If the equilibrium constant for the reaction is 1.2, what is the concentration of the benzoate ion at equilibrium?
Answer: 0.4 M
Explanation: Equilibrium constant expression gives the ratio of product to reactant concentrations.
