उत्तर
Value of Henry’s constant KH increases with increase in temperature.
Explanation:
According to Henry’s law, the solubility of a gas in a liquid at constant temperature is exactly proportional to the partial pressure (x) of the gas present above the surface of the liquid or solution.
p = KHx
The Henry’s constant (KH) normally increases with temperature at low temperatures, reaches a maximum, and then declines at higher temperatures.
