Answer 1

I only got the one answer

Different gases have different K

H

values at the same temperature. This suggests that K

H

is a function of the nature of the gas.

∴ Statement (A) and (D) both are correct.

The most commonly used form of Henry’s law states that “the partial pressure of the gas in vapour phase (p) is proportional to the mole fraction of the gas (x) in the solution” and is expressed as:

p=K

H

X

Here K

H

is Henry’s law constant.

∴ Statement (C) is correct.

Thus, K

H

is directly proportional to the pressure.

More is K

H

less is solubility, lesser solubility is at higher temperature.

So, more is the temperature, more is the K

H

.
