The Reaction Quotient 9 of 10 > - Review Constants Periodic Table When conducting chemical reactions in the lab or in industrial processes, it can be important to know whether a reaction has reached equilibrium By measuring the reaction quotient, Q. of a chemical reaction and comparing it to the equilibrium constant, K, we can identify whether a reaction is at equilibrium Correct Q is less than K, the ratio of products to reactants is smaller than at equilibrium. In...
