Question

For an equlibrium $H_{2}O\left(S\right)\leftrightharpoons H_{2}O\left(l\right)$ which of the following statements 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 increases or decrease the degree of advancement of the reaction depending upon the temperature of the system

Answer 1

The correct option is B More of ice melts if pressure on the system is increased

According to le chatelier's principle, if a dyanmic eqilibrium is disturbed by changing some physical conditions then the equilibrium acts in such a way so that it can minimize the affect and restore the equilibrium again.

Now if pressure is increased then the given equilibrium will go in forward direction so as to minimize the the pressure as volume of $H_{2}O\left(l\right)$ is less than the volume of $H_{2}O\left(s\right)$.
