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
(1) [(0.75)3(0.25)] ÷ [(1.00)2(1.00)]
(2) [(0.75)3(0.25)] ÷ [(0.50)2(0.75)]
(3) [(0.75)3(0.25)] ÷ [(0.50)2(0.25)]
(4) [(0.75)3(0.25)] ÷ [(0.75)2(0.25)]
