A sample of iron(II) sulfate was heated in an evacuated container to 920 K, where the following reactions occurred. 2 FeSO4(s) reverse reaction arrow Fe2O3(s) + SO3(g) + SO2(g)
reaction a
SO3(g) reverse reaction arrow SO2(g) + 1/2 O2(g)
reaction b
After equilibrium was reached, the total pressure was 0.836 atm and the partial pressure of oxygen was 0.0275 atm. Calculate Kp for each of these reactions.
