When the pressure of a sample of gas is increased from 0.25 to 200 atm at constant temperature, its volume decreases from 4.0 l to 6 ml. What could cause the deviation from Boyle's law?

Boyle's law predicts V = (0.25 × 4.0)/200 = 0.005 l = 5 ml at 200 atm; the observed 6 ml is larger than ideal, i.e. Z > 1 at high pressure. Positive deviation at high pressure arises because the finite volume of the molecules is a significant fraction of the container volume there. Ans: (c)
