Problem
A mixture containing 0.50 mol CH₄ and 0.50 mol SO₂ is held in a 10.0 L rigid container at 230 K. The measured pressure is 0.45 atm lower than the pressure predicted for an ideal gas mixture.
(a) Calculate the pressure predicted by the ideal gas law for this mixture.
(b) Determine the percentage by which the measured pressure is lower than the ideal value.
