Physical Chemistry Chapter 1 Chapter 1 THERMODYNAMICS A macroscopic science, the study of two physical quantities, energy and entropy Energy: the capacity to do work Entropy: a measure of the disorder of a system Thermodynamics is particularly concerned with the interconversion of energy as heat and work. Thermodynamics determines the potential for chemical change, not the rate of chemical change
1 A macroscopic science, the study of two physical quantities, energy and entropy. Chapter 1 THERMODYNAMICS Energy: the capacity to do work Entropy: a measure of the disorder of a system Thermodynamics is particularly concerned with the interconversion of energy as heat and work. Thermodynamics determines the potentialfor chemical change, not the rate of chemical change. Physical Chemistry Chapter 1
