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 ΔH0 of a reaction using tables of Δf H appreciate the origin of heat release in net bond breakage explain the origin of gas expansion and heat transfer in terms of probability understand the microscopic definition of entropy in terms of the number of ways of arranging a system define both the 1st and 2nd laws of thermodynamics predict the entropy changes between some simple chemical systems calculate ΔS of a reaction using tables of standard entropies calculate Δuniv S or ΔG of a reaction and predict spontaneity understand the relationship between Δuniv S and ΔG calculate ΔG0 based on values of ΔH0 and ΔS0 or from values of Δf G0 explain the effects of temperature and pressure on ΔG0 explain in principle how one maximizes the useful work obtainable from a chemical reaction
