The heat of neutralisation of a strong base and a strong acid is 13.7 kcal. The heat released when 0.6 mol HCl solution is added to 0.25 mol of NaOH is-

Options

A. 3.425 kcal
B. 8.22 kcal
C. 11.645 kcal
D. 13.7 kcal

Answer

A

Explanation

`HCl(aq)+NaOH(aq)toNaCl(aq)+H_(2)O(l),DeltaH^(0)=-13.7kcal`
`0.25" mol "HCl(aq)+0.25" mol "NaOH(aq) to 0.25" mol "NaCl(aq)+0.25" mol "H_(2)O(l),DeltaH^(0)=-13.7xx0.25=-3.415kcal`
`therefore`Amount of heat released=3,425 kcal.
