Topics and learning outcomes
Introduction to Chemical Energetics
identify the system and the surroundings in a chemical process
identify the ways in which energy is transferred in a chemical process
identify the sign of heat and work in chemical processes
give examples of chemical reactions that do work
calculate energies in Joules or Calories
calculate the energy required to change the temperature of a substance using its heat capacity
calculate the energy released or absorbed by a reaction from data obtained using a bomb calorimeter
explain the origin of the heat of reaction
understand the relationship between internal energy and enthalpy
calculate ΔH of a reaction using Hess's Law of heat summation
calculate ΔH^{0} of a reaction using tables of Δ_{f} H
appreciate the origin of heat release in net bond breakage
explain the origin of gas expansion and heat transfer in terms of probability
