They struggle to connect the value of a large K to a reaction proceeding essentially to completion. This lack of connection leads students to use ineffective mathematical routines and then incorrectly calculate the concentration of the product in solution.

this unit is difficult. rice tables are hard. making connections between reactions and mathematical routines is a struggle for students.

Teachers can ensure that students understand that the first step in making thermodynamic favorability predictions is to define and interrelate enthalpy, entropy, and Gibbs free energy in relation to driving chemical or physical processes

just memorizing the type isn't enough now

Students may struggle to figure out which forces are actually important and present in a molecule

Students will struggle to identify bonds broken or formed in a chemical reaction and then go connect that to the bond enthalpy calculations. Teachers should be sure to emphasize the micro to macro connection of molecule to system.
