91. Among the elements Ca, Mg, P and Cl, the order of increasing atomic radii is
(1) Mg < Ca < Cl < P (2) Cl < P < Mg < Ca
(3) P < Cl < Ca < Mg (4) Ca < Mg < P < Cl
92. The reaction
2A(g) + B(g) ⇌ 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
(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)]
