Equal volumes of molar hydrochloric acid and sulphuric acid are neutralized by dil. `NaOH` solution and `x` Kcal and `y` Kcal of heat are liberated respectively. Which of the following is true?

Options

A. x=y
B. x=y/2
C. x=2y
D. None of the above

Answer

B

Explanation

By equal volumes of molar HCl and `H_(2)SO_(4)` the ratio of `H^(+)` ions furnished = 1 : 2
`therefore` Ratio of heat liberated `=(x)/(y)=(1)/(2)rArr x=(y)/(2)`.
