ChemistrySingle correct+4 / -1Question 37 of 90

The increase of pressure on ice ⇌ water system at constant temperature will lead to :

no effect on the equilibrium

a decrease in the entropy of the system

a shift of the equilibrium in the forward direction

an increase in the Gibbs energy of the system

Answer and worked solution

Official answer: C

Water is denser than ice, so higher pressure favours the smaller volume: ice melts and the equilibrium shifts forward (Le Chatelier).
