paragraph_text: Forward reactions
  
  Reactions that proceed in the forward direction to approach equilibrium are often called spontaneous reactions, that is, Δ G {\displaystyle \Delta G} is negative, which means that if they occur at constant temperature and pressure, they decrease the Gibbs free energy of the reaction. They do not require much energy to proceed in the forward direction. Most reactions are forward reactions. Examples:
