The chemical reaction, `2AgCl_((s))+H_(2(g))to2HCl_((aq))+2Ag_((s))` taking place in a galvanic cell is represented by the notationA. `Pt|H_(2(g)),1"bar"|1M" "KCl_((aq))//AgCl_((s))|Ag_((s))`B. `Pt_((s))|H_(2(g)),1"bar"|1M" "HCl_((aq))||1MAg_((aq))^(+)|Ag_((s))`C. `Pt_((s))|H_(2(g)),1"bar"|1M" "HCl_((aq))|AgCl_((s))|Ag_((s))`D. `Pt_((s))|H_(2(g)),1"bar"|1M" "HCl_((aq))|Ag_((s))|AgCl_((s))` |

Answer» Correct Answer - B `2AgCl_((s))+H_(2(g))to2HCl_((aq))+2Ag_((s))` the activities of solids and liquid are takes as unity and at low concentrations, the activity of a solute is approximated to its molarity. The cell reaction will be `Pt_((s))|H_(2(g)),1"bar"|H_((aq))^(+)1M|AgCl_((aq))1M|Ag_((s))`. |
