<s>[INST] The formation of 1 mol of liquid water from the elements hydrogen and oxygen at 25.0°C and 1 atm follows:

H2(g) + 1/2O2(g) → H2O(l)

The standard enthalpy of formation is -285.8 kJ/mol.

A.  Calculate the reaction quotient (Q) for the production of water at the partial pressures listed below.


| Species | Partial Pressure (atm) |
| --- | --- |
| H2 | 0.040 atm |
| O2 | 0.80 atm |
| H2O | 0.030 atm |

B. Calculate the standard free energy (ΔG) using the standard enthalpy (ΔH) of formation and the standard entropy change (ΔS) at 25.0°C (298 K) for the reaction.[/INST]
