Question

Mole fraction of a gas in water is 0.001 at stp determine its henry's law constant

Answer 1

Mole fraction of gas ,$\bold{x_{solute}}$ = 0.001

∵ according to Henry's law,
$\bold{P = K_H\times x_{solute}}$
Where P is pressure of gas , KH is Henry's constant .
∵ we have given gas at STP
∴ pressure = 1 atm or 0.987 bar

Now, 1 atm = $\bold{K_H}$ × 0.001
⇒ $\bold{K_H}$ = 1000 atm

Hence, Henry's constant = 1000 atm
