Answered: Which is the exothermic direction in… bartleby

WebAn exothermic reaction is a chemical reaction that releases energy in the form of heat or light. During an exothermic reaction, the reactants have more energy stored in their chemical bonds than the products, so the excess energy is released into the surroundings, resulting in an increase in temperature. In an exothermic reaction, the enthalpy ... http://scienceline.ucsb.edu/getkey.php?key=6501

Did you know?

WebDue to bonds breaking and forming during various processes (changes in state, chemical reactions), there is usually a change in energy. If the energy of the forming bonds is greater than the energy of the breaking bonds, then energy is released. This is known as an exothermic reaction. WebBond Energy What makes a reaction endothermic or exothermic? Why? Chemical reactions can be a lot like playing with Legos ® —you must take apart part of your last creation before you can replace it with something new.
