Consider two related reactions with the following Gibbs free energy profiles. In Reaction (A), the reactant has four energetically similar conformers, while in Reaction (B) there is only 1 predominant reactant conformer. In each case, the lowest energy reactant (R) and product (P) conformers are indicated by a red circle. Which of the following statement is true about the equilibrium constants [P]/[R] for the two reactions?a. Reaction A would have a larger equilibrium constant because the reactant state is characterised by...

2. Kinetics of an Oscillating Reaction Oscillating reactions are a special kind of chemical reactions and are characterized by an elementary reaction in which at least one of the reactant is also a product. An example of a series of elementary reactions of an oscilating reaction is below: ka (a) Identify the autocatalytic reacton i.e, a reaction in which the products and reactants share atleast one common ingredient) (b) Identify the reactants, intermediates, and products for the overall reaction described...
