By Maryam Hussain In total, there are four requirements for the occurrence of a chemical reaction. The first requirement is: to bring the molecules of the reactants in the vicinity of each other. The next requirement is: the molecules that have to react with each other, must collide with one another. That is why we stir liquid-liquid, solid powder-liquid, solid powder-gas, gas-gas & solid powder-powder reactants. The next requirement is: the molecules that have to react with each other, must collide with sufficient energy to initiate the process of breaking and forming bonds . This energy is called the energy of activation. That is why we heat or pre-heat or heat the reactants Or cool or pre-cool the reactants. We also bring the energy level up to the required level by introducing the reactants with suitable catalysts with or without heating or cooling. The next requirement is: the molecules that have to react with each other, must collide in an orientation that...
