## How to Use the Gibbs-Helmholtz Equation Calculator?

Navigating through the calculator is a breeze! Follow the guide below for accurate results:

**ΔH (Enthalpy Change)**- Input the enthalpy change of the reaction in Joules per mole (J/mol).**T (Temperature)**- Insert the absolute temperature in Kelvin (K), ensuring it’s above 0 K.**ΔS (Entropy Change)**- Enter the entropy change in Joules per mole per Kelvin (J/(mol·K)).**Calculate**- Calculation would be made automatically and you will get instant result.

## What is the Gibbs-Helmholtz Equation?

The Gibbs-Helmholtz equation is a fundamental concept in thermodynamics, representing the relationship between enthalpy, entropy, and temperature. It’s given by:

\Delta G = \Delta H - T \Delta SHere, ΔG denotes the Gibbs free energy change, signaling whether a reaction is spontaneous or non-spontaneous. This equation offers a window into the balance of energy transformations, applicable across various scientific fields.

## Formulas and Examples

Understanding the Gibbs-Helmholtz equation is pivotal for exploring chemical reactions. Here are practical examples and interpretations:

Example:

- ΔH: -200 J/mol
- T: 298 K
- ΔS: 0.1 J/(mol·K)
- You will get ΔG = 170.2 J/mol

The calculator is an invaluable companion for everyone, from students to researchers, providing insights and elucidating the complexities of thermodynamics.
