A solution of `200 mL` of `1 M KOH` is added to `200 mL` of `1 M HCl` and the mixture is well shaken. The rise in temperature `T_(1)` is noted. The experiment is repeated by using `100 mL` of each solution and increase in temperature `T_(2)` is again noted. Which of the following is correct?

Options

A. `T_(1)=T_(2)`
B. `T_(2)` is twice as large as `T_(1)`
C. `T_(1)` is twice as large as `T_(2)`
D. `T_(1)` is four times as large as `T_(2)`

Answer

A

Explanation

Heat of neutralisation for strong acid with strong base is always constant, hence `T_(1)=T_(2)`.
