The reaction, 2A(g)+B(g)3C(g)+D(g)\mathrm{2A(g) + B(g) \rightleftharpoons 3C(g) + D(g)} is begun with the concentrations of A and B both at an initial value of 1.00 M. When equilibrium is reached, the concentration of D is measured and found to be 0.25 M. The value for the equilibrium constant for this reaction is given by the expression:
