About This Tool
The Gibbs Free Energy Calculator is a user-friendly online tool designed to help chemists, students, and researchers quickly determine the spontaneity of chemical reactions by calculating ΔG. By inputting temperature, standard Gibbs free energy, and reaction quotient, users receive an immediate result and a clear explanation of the reaction's thermodynamic favorability.
This tool automates the fundamental thermodynamic formula GQ = ΔG° + RT ln Q, supporting precise calculations under various conditions. Its intuitive interface allows for real-time updates, making it suitable for educational demonstrations or professional analysis.
Whether you're evaluating reaction feasibility in the lab or teaching students about thermodynamics, this calculator provides accurate results, helpful insights, and supports multiple units and languages for global accessibility.
How to Use
1. Enter the temperature in Kelvin (e.g., 298.15).
2. Input the standard Gibbs free energy (ΔG°) in kJ/mol.
3. Specify the reaction quotient (Q), if known (default 1).
4. View the calculated Gibbs Free Energy (ΔG) and interpret whether the reaction is spontaneous.
