Question

The answers are already given below. Show the solutions how the answers in a and b were obtained.

Calculate
a. AG" and
b. AG750°C
for the following reaction
2 NO(g) +0,(g) = 2 NO,(g)
which is important in the formation of urban smog. Assume that AH and AS do not change between 25.0°C and 750°C and use
these data:
• S(NO) = 210.8 J/(mol•K),
• S(02) = 205.2 J/(mol•K),
• S°(NO2) = 240.1 J/(mol•K),
• AH°(NO2) = 33.2 kJ/mol, and
• AH°: (NO) = 91.3 kJ/mol.
