Understanding This Calculator

Chemical Reaction Formulas

Key thermodynamic and kinetic equations.

  • Moles (n) = Mass (m) / Molar Mass (M)
  • Gibbs Free Energy (ΔG) = ΔH - TΔS
  • Arrhenius Equ. (k) = A × e^(-Ea / RT)

Example 1

Mass: 18g Water (M=18g/mol)

  • n = 18 / 18 = 1 mol

Example 2 (Gibbs)

ΔH = -50 kJ, T = 300K, ΔS = 0.1 kJ/K

  • ΔG = -50 - (300 × 0.1) = -50 - 30 = -80 kJ (Spontaneous)

How to Use

  • Enter mass and molar mass for moles.
  • Enter enthalpy, entropy, temperature for Gibbs energy.
