Henry law is obeyed by a gas when gas has high
a) pressure
b) temperature
c) solubility
d) non of the above

Option b

Explanation:

Henry law describes solubility of gases in liquids.

According to Henry's law, amount of gas dissolved in a liquid depends upon its partial pressure above the liquids.

Mathematically, Henry's law is represented as:

C = K × P

Where,

C = Solubility of gas or concentration of gas in liquids

K = Henry's constant

P = Partial pressure of the gas over the liquid

For, Henry's law to be valid, pressure should be not too high and temperature should not be too low. Henry's law is also valid in case of low dissolved gas concentrations.

So, among the given options, option b, temperature is correct.
