# Gibbs Free Energy Calculator

## What is Gibbs free energy?

Gibbs free energy is a thermodynamic quantity that measures the potential of a system to do work. It is equal to the enthalpy of the system minus the product of the temperature and the entropy of the system.

## Gibbs free energy equation

The Gibbs free energy equation is G = H - TS, where G is the Gibbs free energy, H is the enthalpy, T is the temperature, and S is the entropy.

## Is negative Gibbs free energy spontaneous?

Yes, a negative Gibbs free energy indicates that a reaction is spontaneous.

## How to calculate Gibbs free energy?

Gibbs free energy can be calculated by subtracting the product of the temperature and the entropy of the system from the enthalpy of the system.

## What does Gibbs free energy tell us?

Gibbs free energy tells us the potential of a system to do work and whether a reaction is spontaneous or not.

## How does Gibbs free energy predict spontaneity apex?

Gibbs free energy predicts spontaneity by measuring the potential of a system to do work. A negative Gibbs free energy indicates that a reaction is spontaneous.

## How to calculate Gibbs free energy of a reaction?

Gibbs free energy of a reaction can be calculated by subtracting the product of the temperature and the entropy of the reaction from the enthalpy of the reaction.

## Gibbs free energy units?

The units of Gibbs free energy are joules per mole (J/mol).
