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 . Given HCl + NaOH to NaCl + H_(2)O + 57 kJ CH_(3) COOH + NH_(4) OH to CH_(3) COO NH_(4) + H_(2) O + 48.1 kJ DeltaH for 2H_(2)O (l) to 2 H^(+) (aq) + 2 OH^(-) (aq) is 114 kJ
Answer» Solution :As we know `H^(+) + OH^(-) to H_(2) O "" Delta H = -57` `IMPLIES 2 H^(+) + 2OH^(-) to 2H_(2)O Delta H = -57 XX 2` `implies 2 H_(2) O to 2H^(+) + 2 OH^(-) Delta H = 114 kJ`
