For the following reaction
H₂(g) + 12(g) = 2HI(g)
=
AH° -10.64 kJ/mol and AS° = 21.48 J/
mol K. A closed container in which P_H₂
= P_l₂ = 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? Assume AH° and AS° are
temperature independent.
