question

Ferrous sulfate undergoes a thermal decomposition as follows: 2FeSO_4 (s) = Fe_2O_3 (s) + SO_2 (g) + SO_3 (g) At 929°K the total gas pressure is 0.9atmwith both solids present. (a) CalculateK_pfor this temperature. (b) Calculate the equilibrium total pressure that will be obtained if excess ferrous sulfate is placed in a flask at 929°K, which contains an initial SO_2 pressure of 0.6atm.

  1. K_p = 0.35 atm^2, Total pressure = 1.4 atm
  2. K_p = 0.25 atm^2, Total pressure = 1.2 atm
  3. K_p = 0.5 atm^2, Total pressure = 1.5 atm
  4. K_p = 0.075 atm^2, Total pressure = 0.7 atm
  5. K_p = 0.55 atm^2, Total pressure = 1.6 atm
  6. K_p = 0.4 atm^2, Total pressure = 1.0 atm
  7. K_p = 0.1 atm^2, Total pressure = 0.8 atm
  8. K_p = 0.3 atm^2, Total pressure = 1.3 atm
  9. K_p = 0.15 atm^2, Total pressure = 0.95 atm
  10. K_p = 0.203 atm^2, Total pressure = 1.082 atm
