WebJun 19, 2024 · Break the S − H bond of the thiol of CoA. Break the C − C bond of pyruvate. Form a C = O bond of carbon dioxide. Form a C − S bond of acetyl-CoA. This means that the enthalpy of formation: Δ H = ( 346 + 363) − ( 799 + 272) = − 362 k J / m o l. That is, this reaction releases 362 k J / m o l worth of energy. WebDec 1, 2024 · (a) If bond formation releases more energy than is required in the bond breaking (E f > E b), ΔH = E b – E f = negative. The reaction is exothermic. (b) If bond breaking requires more energy than the energy …
