Which one of the following gases has the lowest value of Henry’s law constant?
A.
$${N_2}$$
B.
$$He$$
C.
$${H_2}$$
D.
$$C{O_2}$$
Answer :
$$C{O_2}$$
Solution :
According to Henry’s law the mass of a gas dissolved per unit volume of solvent is proportional to the pressure of the gas at constant temperature $$m = Kp$$ i.e. as the solubility increases, value of Henry’s law constant decreases. Since $$C{O_2}$$ is most soluble in water among the given set of gases. Therefore $$C{O_2}$$ has the lowest value of Henry’s law constant.
