Consider the chemical reaction and thermochemical information
and initial partial pressures of the reaction components given
below:
2H2O(g) + 2Cl2(g) ⇌ 4HCl(g) +
O2(g)
ΔHf° (kJ/mol) | S° (J mol-1 K-1) | P (atm) | |||
H2O | -241.83 | 188.84 | 0.524 | ||
Cl2 | 0.00 | 223.08 | 0.538 | ||
HCl | -92.31 | 186.90 | 8.45 | ||
O2 | 0.00 | 205.70 | 5.80 |
Determine ΔG (in kJ) for this reaction at 443.18 K. Assume
ΔH°f and S° do not vary as a function of temperature.
Report your answer to two decimal places in standard notation (i.e.
123.45 kJ).
