This is a Biophysical Chemistry Question What is the difference between the heat capacity of a substance and the heat capacity change of a reaction? Why is it important to know whether a reaction has an overall heat capacity change?
The question is given like this, it is not incomplete. There is no heat capacity of the calorimeter given. Can it be solved without that? It is high school chemistry so maybe it can be solved in an easier way? Many thanks.
