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

Explanation

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`
