For the following reaction H₂(g) + I₂(g) ⇌ 2HI(g) ∆H° = -10.64 kJ/mol and ∆S° = 21.48 J/mol･K. A closed container in which P_H₂ = P_I₂ = 0.100 atm and P_HI = 0.500 atm is heated to 855 °C at constant pressure. After equilibrium is attained at that temperature, what is the pressure of HI in atm? To solve the following, you should assume ∆H° and ∆S° are temperature independent.
