Question #34439

Hi all,
We have been doing an experiment surrounding measuring the enthalpy change of a sodium hydroxide and hydrochloric acid heats of neutralisation reaction at a range of different initial temperatures, from 5 to 70 degrees.

It turns out the trend is exponential - that is when the initial temperature is plotted on the x axis and the enthalpy change on the y axis, the line of best fit is exponential. We have been assured this is correct, but can't quite grasp why. Would any of you be able to give us a hand?

Thanks!
