Question

The reaction quotient $\left(Q\right)$ predicts ____________ .

• A. the direction of equilibrium to be attained
• B. the ratio of activities at equilibrium, i.e., $K_c$
• C. the ratio of activities at any time
• D. all of the above

Answer 1

The correct option is D all of the above

The reaction quotient aids in figuring out in which direction, a reaction is likely to proceed, given, either the pressures or the concentrations of the reactants and the products. The $\left(Q\right)$ value can be compared to the equilibrium constant, $\left(K\right)$, to determine the direction of the reaction that is taking place, and the ratio of activities at any time.
