Given : H^(+)(aq, 1M)+e rarr(1)/(2)H_(2)("g, 1atm"), E^(@)=0.00V Hg_(2)Cl_(2)(s)+2e rarr Hg(l) +2Cl^(-)(aq, 1M), E^(@)=+0.27V In which of following galvanic cell, the given reaction occurs - H_(2)"(g, 1atm)"+Hg_(2)Cl_(2)(s)rarr 2Hg(l)+2H^(+)(1M)+2Cl^(-)(1M)

Answer»

`Hg|Hg_(2)Cl_(2)(s)|Cl^(-)(1M)||H^(+)(1M)H_(2)("G, 1atm")|PT`
`Hg|Hg_(2)Cl_(2)(s)||H^(+)(1M)|H_(2)("g, 1atm")|Pt`
`Pt|H_(2)("g, 1 atm")|H^(+)(1M)||H_(2)Cl_(2)(s)|Hg`
`Pt|H_(2)("g, 1atm")H^(+)(1M)||Cl^(-)(1M)|Hg_(2)Cl_(2)(s)|Hg`
