text: A large reorganization energy can make reactions of this type that are strongly exergonic enter an inverted region.
full_question: A large reorganization energy can make reactions of this type that are strongly exergonic enter an inverted region. Cofactor recycling is used in enzymatic catalysis of this type of reaction. These reactions can proceed via an inner-sphere or outer-sphere mechanism. These reactions are balanced for oxygen and hydrogen by adding water, then (*) protons, to each side. A reactivity series is used to determine if these reactions will occur, since they often result in single-displacements. Potassium permanganate is used as an indicator for these reactions. They only occur if the cell potential is positive, when modelled as half-reactions in galvanic cells. For 10 points, name this type of reaction which involves electron transfer.
first_sentence: A large reorganization energy can make reactions of this type that are strongly exergonic enter an inverted region.
raw_answer: redox reactions [or reduction-oxidations; or oxidation-reductions; or electron transfer until it is read; prompt on reductions or oxidations specifically]
