Calculate Δr G for the reaction at 27∘C H2(g)+2Ag+(aq)⇌2Ag(s)+2H+ – InterviewSolution

1.	Calculate Δr G for the reaction at 27∘C H2(g)+2Ag+(aq)⇌2Ag(s)+2H+(aq) Given : pH2 = 0.5 bar;[Ag+]=10−5M;log 2 =0.3 log 2= 0.7, [H+]=10−3M;ΔrG∘[Ag+(aq)]=77.1 kJ/mol
Answer» Calculate $Δ_{r}$ G for the reaction at $27^{\circ} C$ $H_{2} (g) + 2 A g^{+} (a q) ⇌ 2 A g (s) + 2 H^{+} (a q)$ Given : $p_{H_{2}}$ = $0.5 bar; [A g^{+}] = 10^{- 5} M; log 2 =0.3 log 2= 0.7$ , $[H^{+}] = 10^{- 3} M; Δ_{r} G^{\circ} [A g^{+} (a q)] = 77.1 kJ/mol$
