When a gas “X” is dissolved in water, the heat is evolved. Then solubility of ‘X’ will increase at

A.low pressure, high temperature

B.low pressure, low temperature

C.high pressure, high temperature

D.high pressure, low temperature✓ Correct

Explanation

Heat is evolved means exothermic reaction. Exothermic is inversely proportional to the temperature. Gas is dissolved in water so the volume decreases. Pressure is inversely proportional to the volume.
