Question

1. For the reaction

P₄O₁₀(s) + 6H₂O(l)------->4H₃PO₄(aq)

H° = -453 kJ and S° = -16.3 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.

2.
For the reaction

N₂(g) + O₂(g)------>2NO(g)

H° = 181 kJ and S° = 24.9 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.

3. For the reaction

2NO(g) + 2H₂(g)------>N₂(g) + 2H₂O(l)

H° = -752 kJ and S° = -352 J/K

G° would be less than zero 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.
