Question

For the physical equilibrium \[\ce{H2O(s) ⇌ H2O(l)}\] which of the following is true?

Options

• The pressure changes do not affect the equilibrium.

• More ice melts if pressure on the system is increased.

• More liquid freezes if pressure on the system is increased.

• At low pressure, the nature of equilibrium changes to the forward direction.

Answer 1

More ice melts if pressure on the system is increased.

Explanation:

ΔV = −ve for \[\ce{H2O(s) -> H2O(l)}\]

Increase in pressure would cause a decrease in volume. This is achieved by melting ice.
