Henry’s constant (in kbar) for four gases  $\mathrm{\alpha },\mathrm{\beta },\mathrm{\gamma }$ and  $\delta$in water at 298 K is given below :

$\left(\text{ density of water }={10}^3 \mathrm{kg}{ \mathrm{m}}^{-3}\text{ at }298 \mathrm{K}\right)$

This table implies that :

• A

  The pressure of a 55.5 molal solution of $\delta$ is 250 bar

• B

  Solubility of $\gamma$ at 308 K is lower than at 298 K

• C

  The pressure of a 55.5  molal solution of $\gamma$ is 1 bar 

• D

  $\alpha$ has the highest solubility in water at a given pressure
