1.	100 ml 0.5 M H_(2)SO_(4) (strong Acid) is neutralised by 200 ml 0.2 M NH_(4)OH . In a constant pressure calorimeter which results in temperature rise of 1.4 ^(@) C. If heat capacity of calorimeter constant is 1.5 kJ// ^(@) C . Which statement is /are correct .

Answer» Solution :`57 - (x +y) = 48.1` `IMPLIES x + y = 8.9` `implies 4.5 + y = 8.9 implies y = 4.4` `implies ` ENTHALPY of dissociation of `CH_(3) COOH` `=4.4 ` kJ/mol
