Oxygen – usually -2, except when it forms a O-O single bond, a … To identify a redox reaction, we must first calculate the oxidation number of each atom in the reaction. Redox reactions are considered as electron transfer reaction. <> To do this though, we need to first verify that the same number of electrons are involved in both the oxidation and the reduction portions. A spontaneous reaction is a reaction that occurs: 1) by a driving force that favors the product, 2) the free energy of the product is lower than the free energy of the reactant, and/or 3) occurs without any outside ‘help’ such as electrolysis. For example, we can think of the reaction of metallic iron with chlorine gas to form ionic iron(III) chloride as the net transfer of six electrons from two iron atoms to three chlorine molecules: View Identifying REDOX Reactions Worksheet.pdf from BIO 356 at Stony Brook University.
