What it calculates
The “Gibbs Free Energy (ΔG = ΔH − TΔS)” calculator computes ΔG in kJ/mol from 3 parameters: δh, kj/mol, t, k, δs, j/(mol·k).
A standard physics formula used in educational and engineering tasks.
Example calculation
With parameters ΔH, kJ/mol = -100, T, K = 298, ΔS, J/(mol·K) = 50 the result is -114.9 kJ/mol.
