When acids an bases react they liberate some amount of energy which is represented as `DeltaH` neutralization if one equivalent of acid and base reacts. The energy liberated depends on the concentration of acid and base and also on whether the acid is strong or weak. For strong acids and bases, the value is constant and for weaker acids as bases the magnitude is generally lesser. Using this info and the date below answer the question that follow : [Given data : `Delta_("neutralization")HCl//NaOH = - 14 Kcal//eq` (at infinite dil.) `DeltaH_("ionisation")CH_(3)COOH = 2kcal//mol` `DeltaH_("ionisation")NH_(4)OH = 3kcal//eq]` In which of the following will heat released be same ?A. `HCl (0.2 M, 500 ml)`, mixed with `NaOH (0.3 M, 500 ml)`B. `HNO_(3)(0.5M, 200 ml)` mixed with `KOH (0.4 M, 280 ml)`C. `H_(2)SO_(4)(0.1 M, 200 ml)` mixed with `NaOH (0.3 M, 1000 ml)`D. `CH_(3)COOH (0.1 M, 1000 ml)` mixed with `NaOH (0.3 M, 500 ml)`
