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 this case, the reaction will proceed to the right to create more product and reach equilibrium For the reaction A+bB=cC +dD Conversely, if Q is greater than K, the ratio of products to reactants is larger than at equilibrium. In this case, the reaction will proceed to the left and revert some of the product back to reactants to reach equilibrium. the reaction quotient, Q. is given by the expression Q Q=CD Part B AMB under any conditions. The value of Q is equal to K only at equilibrium The following reaction was carried out in a 2.75 L reaction vessel at 1100 K: C(s) + H2O(g) =CO(g) + H (8) If during the course of the reaction, the vessel is found to contain 5.00 mol of C. 15.8 mol of H20, 3.00 mol of CO and 9.00 mol of H2, what is the reaction quotient Q?
