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 tempe
ratures (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.
1 answer:
Answer:
G° would be negative when temperatures are above 691K
Explanation:
G° could be found as:
G° = H° - TS°
As <em>H° = 98.8 kJ and S° = 143 J/K</em>; G° would be negative when H° < TS°, that is:
H° < TS°
98800J < 143 J/K ₓ T
691K < T
That means <em>G° would be negative when temperatures are above 691K</em>
