4. Consider a reaction vessel filled with the gases, H₂, I2 and HI at 298K under the following partial pressures. PHI 10.0 atm, P12=1.5atm, PH2=2.0atm The gases in the reaction vessel are then allowed to react via the decomposition of HI and formation of H₂ and 12 taking place until an equilibrium is reached. Calculate the reaction quotient and determine the direction of the reaction. Also determine the equilibrium partial pressures of all the three gases. (AG-15.930KJ/mol).

4. Consider a reaction vessel filled with the gases, H₂, I2 and HI at 298K under the following
partial pressures.
PHI 10.0 atm, P12=1.5atm, PH2=2.0atm
The gases in the reaction vessel are then allowed to react via the decomposition of HI and
formation of H₂ and 12 taking place until an equilibrium is reached. Calculate the reaction
quotient and determine the direction of the reaction. Also determine the equilibrium partial
pressures of all the three gases. (AG0-15.930KJ/mol).
