In two connected ways, thermodynamics describes how both physical or chemical processes spontaneously trend towards equilibrium. This post is concerned with showing how free energy (ΔGrxn) changes as the reaction quotient (Q) changes as both trend towards the special condition, equilibrium, described by the constant K.

Balloons that inflate using carbon dioxide produced from the reaction of citric acid and sodium hydrogen carbonate can be used to demonstrate a number of aspects of chemistry. Gas laws were used with the balloons to illustrate limiting reactants, molar mass of gases, and rockets. The endothermic reaction in the balloon was visualized with an infrared camera, and the Green Chemistry aspects of these balloons were considered.
