Unformatted text preview: relate initial to final state variables (p, V, T) for each of these processes. 3) Thermochemistry: Hess’s law, calculation of standard reaction enthalpy changes from standard formation enthalpies and bond dissociation enthalpies. Know the state and formula for elements in their standard reference state. Calculations of standard reaction enthalpies from the temperature change in calorimeter and vice- versa. Calculations of the standard reaction enthalpy change at some temperature using the standard reaction enthalpy change at 298 K (Kirchhoff equation or using the cycle diagram). 4) Know how to calculate changes in entropy for the system, surroundings and universe for: A) processes where P, V, T B) processes where there is a phase change C) processes involving chemical reactions Second L...
