From Wikipedia, the free encyclopedia. The environmental impacts of irrigation relate to the changes in quantity and quality of soil and water as a result of irrigation and the effects on natural and social conditions in river basins and downstream of an irrigation scheme.
Combustion reactions can only be exothermic. In chemical reactions, old bonds are broken to form new ones. Depending on the energy difference between broken and formed bonds, the total reaction energy is either positive or negative.
heat will be absorbed and the products will be formed faster exothermic reaction will undergo spontaneously as it does not require any energy while endothermic reaction has to be supplied with energy to happen therefore exothermic reaction will be faster than endothermic reaction
