Question
For the following reaction: 4NH 3 (g) + 5O 2 (g) 4NO(g) + 6H 2 O(l) Compound H f (kJ mol -1 ) S (J
For the following reaction: 4NH3(g) + 5O2(g) 4NO(g) + 6H2O(l)
| Compound | Hf (kJ mol-1) | S (J mol-1 K-1) | ||
| NH3 (g) | -45.94 | 192.77 | ||
| O2 (g) | 0.00 | 205.70 | ||
| NO (g) | 90.29 | 210.76 | ||
| H2O (l) | -285.83 | 69.91 |
Calculate Grx (in kJ) at 635.25 K for this reaction. Report your answer to two decimal places in standard notation (i.e. 123.45 kJ). Assume Hf and S do not vary as a function of temperature.
