Entropy

Introduction

  • Entropy pretty much can be summed as saying, “more entropy = more ways in can be configured“

Absolute Entropy and Entropy Change

  • Zero entropy is a pure crystalline structure at 0 Kelvin

  • Boltzmann entropy equation: S = klnW

  • W = microscopic arrangements of all molecules and energies in a system

  • k = Boltzmann constant = 1.38 × 10^-23 J/K

  • (delta) S (standard reaction) = (all entropy of products) - (all entropy of reactants)
