Reaction quotient Q = 51
Equilibrium constant K = 250
so Q < K
hence , Reaction will proceed in forward direction to reach the equilibrium
than product concentration is increased i.e " Net gain in Product " option [c] is correct

Select all of the correct statements about reaction quotients and equilibrium constants from the choices below. A reaction quotient equals the equilibrium constant at equilibrium. In a reacting mixture K is the ratio of product to reactant concentrations. As a reaction progresses backwards toward equilibrium K is the lowest value Q attains. K changes as temperature changes, but is independent of concentrations. A reaction quotient is the same as an equilibrium constant. As a reaction progresses...

Use the reaction quotient, Q, to explain why the fraction of dissociation of weak acid, HA, increases when the solution is diluted by a factor of 4. When the system is at equilibrium, Q = [A^-][H^+]/[HA] = K_a. Let's call the concentrations at equilibrium [A^-]e, [H^+]e, and [HA]_e. if the solution is diluted by a factor of 4, the concentrations become [A^-]_e, [H^+]_e, [H^+]_e, and [HA]_e. The reaction quotient becomes Q = K_a. Since Q K_a, the concentrations of products...
