For the reaction

Fe2O3(s) + 3H2(g)2Fe(s) + 3H2O(g)

H° = 98.8 kJ and S° = 143 J/K

G° for this reaction 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.

98800 -(T*143) <0

690.91 <T

So temperature should be above 690.91 k or above 691 k

above 691k

could u do this one please

4HCl(g) + O2(g)2H2O(g) + 2Cl2(g)

H° = -114 kJ and S° = -129 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.
