If enthalpy of vapourisation of Br_2 is +30 kJ mol^(-) , electron gain enthalpy of Br is -325 kJ mol^(-1) and hydration enthalpy of bromide is -339 kJ mol^(-1) calculate the change in enthalpy for the reaction, 1/2Br_(2)(l) + e^(-) overset(aq)(rarr) Br^(-)(aq) .
Enthalpy of neutralisation of H_(3)PO_(3) acid is -106.68kJ//mol using NaOH. If enthaly of neutralisation of HCl by NaOH is -55.84 kJ/mol. Calculate DeltaH_("ionization") " of " H_(3)PO_(3) into its ions
Enthalpy of neutralization is defined as the enthalpy change when 1 mole of acid/base is completely neutralized by base/acid in dilute solution. For strong acid and strong base neutralization net chemical change is H_((aq))^(+) + OH_((aq))^(-) rarr H_(2)O_((l)), Delta H_(r )^(0) -= - 55.84 kJ//mol If enthalpy of neutralization of CH_(3)COOH by NaoH is -49.86 kJ/mol then enthalpy of ionisation of CH_(3)COOH is
