  1. Question 1

    Q1. The van der Waals equation for 1 mole of a real gas is:

    • A) (P + a/V²)(V - b) = RT
    • B) (P - a/V²)(V + b) = RT
    • C) (P + a/V)(V - b) = RT
    • D) (P - a/V)(V + b) = RT

    Answer: (P + a/V²)(V - b) = RT

    Explanation: The van der Waals equation accounts for intermolecular forces (a) and molecular volume (b).
