Question
The slope of a Van’t Hoff plot is proportional to the negative change in this quantity, since the Van’t Hoff equation states (read slowly) “the change in this quantity over R T-squared equals the time derivative of the natural log of K-eq.” The change in this quantity is the same no matter the number of steps a reaction is performed in since it is a state function according to Hess’s law. This quantity equals internal energy plus pressure times volume. By definition, an exothermic reaction has a negative change in this quantity. For 10 points, name this quantity that represents the heat content of a system, symbolized H. ■END■
