For reactions involving strong acids and alkalis, the values of neutralization enthalpies are always very closely similar, with values between -57 and -58 kJ mol-1.So in this question, when equimolar chemicals are given, 50 ml HCl will be excess and only 50 ml will be active.No. Of moles in 100 ml HCl solution, 0.02In 50 ml solution, 0.01No. Of moles in 50 ml KOH solution, 0.01Enthalpy of neutralization is consider -57.9 KJ/mol.So final answer will be -579 J.
