Detailed explanation-1: -These arrows are used to show an equilibrium reaction where the longer arrow points to the side the reaction strongly favors. The top reaction shows the products are strongly favored over the reactants.
Detailed explanation-2: -A reaction arrow just tells you that a change has taken place, and one thing has turned into another. The arrow points from the old thing (the thing that reacted) to the new thing (the thing that formed). The reaction arrow is used in an “equation of reaction". The thing that reacted is called the reactant.
Detailed explanation-3: -The purpose of the curved arrow is to show movement of electrons from one site to another. Electrons move from the tail to the head. Most of the arrows you’ll see have a double-barb at the head, representing the movement of a pair of electrons.
