Question

For the dissolution of gas in solvent at a given temperature, increase in pressure of gas will result in:

Answer 1

In dissolution of gas in solvent, gas is in equilibrium with the liquid solution.

$\text{Rate of dissolution of gas}=\text{Rate of escape of gas from the liquid}$

When the pressure of the gas is increased, population density of the ​gas molecules increases and the equilibrium between gas and liquid ​gets disturbed​ and to restore the equilibrium more gas molecules escape into the solution phase which result in increase in solubility of gas.
