From the following data, mark the option (s) where `Delta H` is correctlt written for the given reaction. Given `H^(+)(aq) + OH^(-)(aq) rarr H_(2)O(l), Delta H = -57.3 kJ` `Delta H_("solution")` of HA(g) = -70.7kJ/mol `Delta H_("solution")` of BOH(g) = 20kJ/mol `Delta H_("ionization")` of HA = 15 kJ/mol and BOH is a strong base Reaction `Delta H_(r)(kJ//mol)`A. `HA(aq)+BOH(aq) rarr BA(aq)+H_(2)O - 42.3`B. `HA(g) + BOH(g) rarr BA(aq)+H_(2)O -93.0`C. `HA(g) rarr H^(+)(aq)+A^(-)(aq)-55.7`D. `B^(+)(aq)+OH^(-)(aq) rarr BOH (aq) - 20.0` |
