All chemical reactions require that certain covalent bonds be broken within the reactants. In order for this to occur, the reactants must have sufficient kinetic energy to overcome the activation energy barrier (EA). There are some reactions that require the input of energy (nonspontaneous), and some reactions that release energy (spontaneous), so they can keep going without added energy - however ALL reactions need energy to get the initial reaction started. Identify if the following reactions are spontaneous (exergonic) or non-spontaneous (endergonic) Energy A AG" Energy ---, AA AG Large E, AG<0 Slow and favorable Small EA, AG40 Fast and favorable Small EA, AG>0 Fast and unfavorable All chemical reactions require that certain covalent bonds be broken within the reactants.
