Key Topics: Thermodynamics

This problem focuses on the Electrical, Environmental and Communications, or EECOM, flight controller and students are introduced to the space shuttle’s CO2 removal process. They will apply several concepts and equations of thermochemistry as they analyze this situation.

Students will:
  • find standard enthalpy change using Hess’s Law;
  • determine the standard entropy change for a reaction;
  • determine the standard free energy change for a reaction;
  • use the sign of the standard free energy change to predict the spontaneity of a reaction; and
  • determine the equilibrium constant for a reaction.
