- Enthalpy of Reaction Calculator (Heats of Formation)Hess's law applied to standard enthalpies of formation at 298.15 KThe standard enthalpy change of any reaction is the sum of the formation enthalpies of the products minus the sum for the…
- Calorimetry Heat Calculator (q = mcΔT)Constant-pressure calorimetry, q = mcΔTA calorimetry experiment measures heat indirectly: you record a temperature change and convert it with q = mcΔT. Enter the mass…
- Gibbs Free Energy CalculatorΔG = ΔH − TΔS; ΔG° = −RT ln K (CODATA 2018 gas constant)Gibbs free energy decides direction. A process runs forward on its own when ΔG is negative, and ΔG = ΔH − TΔS puts a number on…
