Big Idea 5: The laws of thermodynamics describe the essential role of energy and explain and predict the direction of changes in matter.
Enduring Understandings
Enduring understanding 5.C: Breaking bonds requires energy, and making bonds releases energy.
Learning Objectives
LO 5.1 The student is able to create or use graphical representations in order to connect the dependence of potential energy to the distance between atoms and factors, such as bond order (for covalent interactions) and polarity (for intermolecular interactions), which influence the interaction strength [See SP 1.1, 1.4, 7.2, connects to Big Idea 2]
LO 5.8 The student is able to draw qualitativve and quantitative connections between the reaction enthalpy and the energies involved in the breaking and formation of chemical bonds. [See SP 2.3, 7.1, 7.2]
