4. Calculating Ko from percentage dissociation (a) When the following equilibrium was established at a given temperature 20% of the
compound A2B2 was dissociated. This total pressure of the equilibrium mixture was
30 atm. Calculate the value of Ke at this temperature.
A2B2 (g) 2AB (g)
(b) When the following equilibrium was established at a given temperature 75% of the
sulphur trioxide was dissociated. The total pressure of the equilibrium mixture was
10 atm. Calculate the value of Ko at this temperature.
