MCQ (More than One Correct Answer)

-1

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

	$$\alpha $$	$$\beta $$	$$\gamma $$	$$\delta $$
K_H	50	2	2 $$ \times $$ 10^-5	0.5

(density of water = 10³ kg m^-3 at 298 K)
This table implies that :

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

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

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

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