Question
57. For each reaction, calculate AHan ASan and AGan at 25 °C
and state whether or not the reaction is spontaneous. If the reac-
tion is not spontaneous, would a change in temperature make it
spontaneous? If so, should the temperature be raised or lowered
from 25 °C?
a. N,04(8)
b. NH,CI(s)
c. 3 H2(g) + Fe,O3(s) → 2 Fe(s) + 3 H,O(g)
d. N2(g) + 3 H2(8) → 2 NH3(g)
2 NO2(8)
→ HCI(g) + NH;(g)
