Does a neutralisation reaction with higher volumes create more heat?

In a multiple choice question, I assumed that half the volume of 2 acids and bases with constant concentrations would mean half the temperature. The answer suggests there is no change.

Can anyone explain this? I can't understand how presumably half the molecules can produce the same amount of heat.

The question:
- 50cm(^3) of 1M NaOH is neutralised by 50cm of 1M HNO3 to increase the temperature by 6C.
- The experiment is repeated with 25cm(^3) of each

I answered that the resultant temperature would increase by 3, but the answer is 6. Please help
