An equilibrium mixture, at 672°C in a 1155-mL container, involving the chemical system
N2(g) + 3H2(g) 2NH3(g)
is found to contain 9.14 g of N2, 0.707 g of H2, and 0.300 g of NH3. Calculate the equilibrium constant (Keq expressed in terms of the molar concentrations) at the given temperature.
A 5.00-L vessel contained 4.61×10-2 mol of gaseous PCl3, 5.22×10-2 mol of gaseous PCl5, and 6.83×10-2 mol of Cl2 gas at equilibrium at 222°C. Calculate the value of Keq (expressed in terms of the molar concentrations) for the reaction
