3. SO3 (g) The following reaction is important in the manufacture of sulphuric acid: SO2 (g) + 1/2O2(g) At 900 K, 0.0540 moles of sulphur dioxide & 0.0370 moles of oxygen are sealed in a 2.50 L reaction vessel. When equilibrium is reached, the amount of sulphur trioxide is determined to be 0.0430 moles. Calculate the equilibrium (Keq = 49.6 L/mol) concentrations of all three compounds & the value of Keq at 900 K.
