JUU UHUMU UU UHCMlal yumurium Equilibrium Constant and Reaction Quotient At equilibrium, the concentrations of reactants and products can be predicted using the equilibrium constant, Kc, which is a mathematical expression based on the chemical equation. For example, in the reaction aA +B=cC + dD where a, b, c, and d are the stoichiometric coefficients, the equilibrium constant is K. = _CºD [A] [B] where [A], [B], [C], and [D] are the equilibrium concentrations. If the reaction is not at equilibrium, the quantity can still be calculated, but it is called the reaction quotient, Qc, instead of the equilibrium constant, K. [C]”D [A],”B), where each concentration is measured at some arbitrary time t.
A mixture initially contains A, B, and established: in the following concentrations: (A) – 0,350 M B Review Ice ] -0.600 M, and C -0.600 M. The following reaction occurs and A + 2BC At equilibrium, (A) – 0.180 M and C -0.770 M. Calculate the value of the equilibrium constant, ka Express your answer numerically. View Available Hint(s) K = 63.3 Submit Previous Answ ✓ Correct Part B Now consider the reaction A + 2B=C for which in the initial mixture 387 AB2 Is the reaction at equilibrium? If not, in ceed to reach equilibrium? ► View Available Hint(s) The reaction is already at equilibrium. The reaction will proceed in reverse to form The reaction will proceed forward to form pr Submit
