To increase substrate specificity c. To prevent spontaneous oxidation of the iron in the cluster d. a and c e. b and c - ️️e. b and c Two tabby (striped) cats are bred...

Which of the following statements is FALSE? a) The free E barrier in a chemical rxn must be overcome in order for products to form. b) An increase in temp. can result in an increased rxn rate. c) Lowering the free E of the transition state can increase a rxn rate d) At a given temp. & time all molecules in a soln or a sample will have the same E Correct Answer-D In a favorable rxn, the free energy of the products _ the free energy of the reactants. Correct Answer-has no bearing on Cata...
