If `H^(+)+OH^(-)rarrH_(2)O+13.7Kcal` , the heat of neutralisation for complete neutralisation of 1 mole of `H_(2)SO_(4)` by base will be

Options

A. 13.7 kcal
B. 27. 4 kcal
C. 6.85 kcal
D. 3.42 kcal

Answer

B

Explanation

Since, `H_(2)SO_(4)` gives`2H^(+)`, therefore heat of complete neutralisation is `2xx 137` kcal = 274 kcal.
