Lesson Plan: Relationship Between Free Energy and the Equilibrium Constant Mark as Favorite (14 Favorites)
In this lesson, students will explore the relationships between solubility and Keq (specifically Ksp), as well as Keq and ΔG°. First, a guided inquiry activity will introduce the relationship between standard free energy and equilibrium constant with the equation ΔG° = RTlnKeq. Then data collection regarding solubility of potassium nitrate at various temperatures will lead to the calculation of Ksp and ΔGo for the dissolution reaction at those temperatures. Students will manipulate the equations ΔG° = RTlnKeq and ΔG° = ΔH°  TΔS° to derive a linear relationship between 1/T and lnKeq, which will then be graphed to determine values for ΔH° and ΔS°.

Lab: Utilizing Hess's Law Mark as Favorite (33 Favorites)
In this lab, students will use a coffee cup calorimeter to collect data that will allow them to calculate ∆H for two reactions. The first reaction, between sodium bicarbonate and hydrochloric acid is endothermic. The second, between sodium carbonate and hydrochloric pressure, is exothermic. They will then use their experimental values and Hess’s Law to determine ∆H for the decomposition of sodium bicarbonate, compare their calculated value to the theoretical value, and calculate the percent error. This resource includes a prelab presentation and sample calculations.
