Which consequence results when Van der Waals constant 'a' increases significantly in the real gas equation?

A)Ideal gas behavior is approached
B)Intermolecular attraction increases substantially
C)Repulsive forces become more dominant
D)Gas compressibility approaches zero

💡 Explanation

Increased 'a' signifies stronger intermolecular attractions; this elevates internal gas pressure because the molecules cohere more tightly, therefore pressure decreases, rather than the gas behaving ideally with no intermolecular forces.
