Calculate the standard change in free energy for the following redox reactions (See Table A1.1 on Canvas for standard free energies of formation, and Table 7-6 on Canvas for half reactions for the last two reactions).List the metabolic category that the reaction falls into and whether it is aerobic or not. 1. Oxidation of Glycerol with O₂ 2. Oxidation of NO₂ to NO3 with O₂ 3. Oxidation of H₂ to H+ with Fe³+
