CHEM1901 - Resources for Week 9

Topics and Learning Outcomes

  • 1st Law of Thermodynamics
    •  define the types of thermodynamic system
    •  recognise electrical, PV, surface, and elastic (spring) work
    •  express and explain the First Law of Thermodynamics, and use it to carry out energy balances
    •  define heat capacity and manipulate First Law heat capacity expressions
    •  define the terms exothermic and endothermic
    •  explain how a calorimeter and a chemical thermostat work
  • Enthalpy
    •  define enthalpy, and distinguish between CP and CV
    •  recognise and define the enthalpies of solution, formation, atomization, vapourization, condensation, fusion, sublimation and combustion
    •  use Hess’s Law to calculate the enthalpy of an unknown reaction from appropriate data, including standard enthalpies of formation, or estimate it from bond enthalpies
    •  define heat engine, thermodynaic cycle, and the efficiency of a heat engine
    •  recognise the difference between petrol and diesel engine cycles
    •  recognise and distinguish common fuel types, and discuss their advantages and disadvantages in different situations.
  • 2nd Law of Thermodynamics
    •  write down the Second Law of Thermodynamics
    •  define entropy, spontaneous processes and equilibrium
    •  use standard entropies to calculate ΔS for a reaction at standard conditions, and with standard enthalpies of formation, predict whether a reaction will be spontaneous under those conditions
