38) *by increasing the temperature of the solution the solute will dissolve more quickly.

* the nature of solute should be similar to the solvent means if the solute is polar in nature so the solvent should also has polar nature and vice versa for greater solubility .

39) effect of temperature:

temperature is inversly proportional to the solubility of a gas. By increasing the temperature the kinetic energy of gas molecules increases which leads to the escape of gas molecules from the solvent because of the increased kinetic energy. so the solubility of the gas decreases.

effect of pressure:

pressure is directly proportional to the solubility of the gas. as the pressure on the gas molecules increases, they'll come close to each other and the solubility of the gas molecules increases.

p=khc

p= partial pressure

Kh= henry's law constant

c= concentration of gas

40) 0.0666M

41) (35.7*50)/100 = 17.84g

42) 589ppm
