1. The problem statement, all variables and given/known data
In which case of mixing of a strong acid and a base each of 1 N concentration, temperature increase is highest.

A)20ml acid-30ml alkali
B)40ml acid-40ml alkali
C)25ml acid-25ml alkali
D)35ml acid-15ml alkali

2. Relevant equations
Law of Equivalents

3. The attempt at a solution
Using the law of equivalents I have
$N_{1}V_{1}=N_{2}V_{2}$
Since both are 1 N
$∴V_{1}=V_{2}$
So I am now left with options B and C but I don't have any clues how to differentiate between the two. Speaking in layman's term in option B the volume is more so temperature increase will be highest(Fortunately this is correct answer) but I need a scientific reasoning for this.

B is not the only correct answer.

q=mcΔT, solve for ΔT, see if it helps.

I don't know q,m and c. How can I solve it?
