Description
At the end of this activity, students should be able to: – use the laws of probability to explain the spontaneity of chemical and physical changes – explain the concept of entropy as a measure of disorder at the molecular level – discuss the entropy changes caused by chemical and physical processes – use standard entropy values to calculate standard entropy changes for reactions – explain how the entropy change of a system is affected by temperature, phase change or the stoichiometry of gaseous reactions – use enthalpy change and temperature to determine the enthalpy change for the surroundings – use a calculated total entropy change to predict whether a reaction is spontaneous or not.
