Choose the correct statement about Henry's constant $(K_H)$.
$I$. $K_H$ increases with increase in temperature generally.
$II$. $K_H$ decreases with increase in temperature generally.
$III$. $K_H$ is the characteristic constant of the gas-solvent system.

$5.5 \text{ mg}$ of nitrogen gas dissolves in $180 \text{ g}$ of water at $273 \text{ K}$ and $1 \text{ atm}$ pressure due to nitrogen gas. The mole fraction of nitrogen in $180 \text{ g}$ of water at $5 \text{ atm}$ nitrogen pressure is approximately:

In which of the following salts,the solubility increases appreciably with an increase in temperature?

Calculate the quantity of $CO_2$ required to prepare $1 \,L$ of soda water when the soda water is packed under $2 \,atm$ of $CO_2$. [Henry's law constant for $CO_2$ is $1.67 \times 10^8 \,Pa$] (in $\,g$)

The values of the Henry's law constant of $Ar$,$CO_{2}$,$CH_{4}$ and $O_{2}$ in water at $25^{\circ} C$ are $40.30$,$1.67$,$0.41$ and $34.86 \ kbar$,respectively. The order of their solubility in water at the same temperature and pressure is

$A$ company dissolves '$X$' amount of $CO_{2}$ at $298 \ K$ in $1 \ L$ of water to prepare soda water. $X = ........ \ \times 10^{-3} \ g$ (nearest integer).
(Given: partial pressure of $CO_{2}$ at $298 \ K = 0.835 \ bar$.
Henry's law constant for $CO_{2}$ at $298 \ K = 1.67 \ kbar$.
Atomic mass of $H$,$C$ and $O$ is $1$,$12$ and $16 \ g \ mol^{-1}$,respectively.)
