From the following date , mark the opation(s) where `Delta H` is correctly written for the given reaction . Given: `H+(aq) +OH-(aq) to H_(2)O(l),` `DeltaH=-57.3 kJ` `DeltaH_(solution) HA(g)=-70.7 kJ"mole"` `DeltaH_(solution) BOH(g)=- 20 kJ"mole"` `DeltaH_("ionzatoin") ` of `HA=15 kJ//"mole"` and BOH is a strong base. A. `{:("Reaction",DeltaH_(r)(KJ//"mol")),(HA(aq) + BOH(aq) rarr BA(aq) + H_(2)O,-42.3):}`B. `{:("Reaction",DeltaH_(r)(KJ//"mol")),(HA(q) + BOH(q) rarr BA(aq) + H_(2)O,-93):}`C. `{:("Reaction",DeltaH_(r)(KJ//"mol")),(HA(q) rarr H^(+)(aq)=A^(-)(aq),-55.7):}`D. `{:("Reaction",DeltaH_(r)(KJ//"mol")),(B^(+)(aq)+OH^(-)(aq) rarr BOH(aq),-20):}` |
