Given the change in temperature during the course of a reaction what formula would you use to calculate qp? In a coffee-cup calorimeter the heat absorbed by the water is equal to the heat given off by the reaction of the solutes. That is, the enthalpy of a reaction, AH is defined as the quantity of heat transferred under constant pressure, AH = -qp Given the change in temperature during the course of a reaction what formula would you use...
