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.
