11) a) For the reaction

H2(g) + Cl2(g) ---> 2 HCl(g)

G° = -190.8 kJ and S° = 20.0 J/K at 309 K and 1 atm.

This reaction is (reactant, product)  favored under standard conditions at 309 K.

The standard enthalpy change for the reaction of 2.34 moles of H2(g) at this temperature would be ___ kJ.

b) For the reaction

CO(g) + Cl2(g) ---> COCl2(g)

H° = -108 kJ and S° = -137 J/K

G° would be negative at temperatures (above, below) ___ K.

Enter above or below in the first box and enter the temperature in the second box. Assume that H° and S° are constant.
