Question

For the equilibrium, $H_{2}O\left(s\right)\rightleftharpoons H_{2}O\left(l\right)$, which of the following statement is true?

• A. The pressure changes do not affect the equilibrium.
• B. More of ice melts, if pressure on the system is increased.
• C. More of liquid freezes, if pressure on the system is increased.
• D. The pressure changes may increase or decrease the degree of advancement of the reaction depending upon the temperature of the system.

Answer 1

The correct option is A The pressure changes do not affect the equilibrium.

$H_{2}O\left(s\right)\rightleftharpoons H_{2}O\left(l\right)$

Here in equilibrium only solids and liquids are present. Since pressure can't change concentration of solids and liquids. So pressure don't have any effect on equilibrium.
