The surface of copper gets tarnished by the formation of copper oxide. N2 gas was passed to prevent the
oxide formation during heating of copper at 1250 K. However, the N2 gas contains 1 mole % of water
vapour as impurity. The water vapour oxidises copper as per the reaction given below:

is the minimum partial pressure of H2 (in bar) needed to prevent the oxidation at 1250 K. The value of
ln  is ____.
(Given: total pressure = 1 bar, R (universal gas constant) = 8 J K-1 mol-1, ln(10) = 2.3. Cu(s) and Cu2O(s)
are mutually immiscible.
At 1250 K: 2Cu(s) + ½ O2(g) --> Cu2O(s); ΔGθ = − 78,000 J mol−1
H2(g) + ½ O2(g) --> H2O(g); ΔGθ = − 1,78,000 J mol−1; G is the Gibbs energy)
    Correct answer is '-14.6'. Can you explain this answer?
