Introduction
Gibbs energy or Gibbs function, G, is a state function and an extensive property which helps to find out the direction of the spontaneous change of processes taking place in open and closed systems.
Pre-Requisites:
Enthalpy, lattice structure, energy, exothermic, endothermic
Activity:
Lighting a matchstick.
Real Life Question:
How do products form when reactants come in contact?
