Expert Solution
Step 1

The Answer to the Following question is-

 

b) Henry's Law Constant KH = e-∆GRT
Now calculating ∆G for the given reaction at 25° C.

Converting 0°C into Kelin T= 273 + 25 = 298K

H2S (g)↔H2S (aq)

∆G°=∆H°-T∆S°

∆H°=∆H°f(Product)-∆H°f(reactant)=(-39.25KJ/mol)-(-20.63KJ/mol)=-19.12KJ/mol

∆S°=∆S°f(product)-∆S°f(reactant)=121.3J/mol.K-205.7 J/mol.K=-84.4 J/mol.K

∆S°=-84.4 J/mol.K=-0.0844KJ/mol.K

T∆S=298×(-0.0844 KJ/mol.K)=-25.15 KJ/mol

∆G°=∆H°-T∆S°

∆G°= -19.12 KJ/mol - (-25.15 kJ/mol)= 6.03 KJ/mol

Putting the value in the KH we get:

KH=e-6.030.008314×298=e-2.43=0.088
