**Problem 71: Reaction Gibbs Free Energy Calculation**

Consider the reaction:

\[ \text{CH}_3\text{OH}(g) \rightleftharpoons \text{CO}(g) + 2 \text{H}_2(g) \]

Calculate \( \Delta G \) for this reaction at 25°C under the following conditions:

i. \( P_{\text{CH}_3\text{OH}} = 0.855 \, \text{atm} \)

ii. \( P_{\text{CO}} = 0.125 \, \text{atm} \)

iii. \( P_{\text{H}_2} = 0.183 \, \text{atm} \)

**Note:** This problem involves calculating the change in Gibbs free energy (\( \Delta G \)) for the given reaction using the provided partial pressures of the substances at 25°C.
