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...

3. [10 marks] We've covered the definition of Gibbs free energy, Helmholtz free energy, entropy, and enthalpy. There is also something called their fundamental equations. a) [8 marks] Use online resources and your peers to determine the total differential form of each of these terms. For example, if we're looking at Gibbs free energy, defined as G = H – TS, then determine what dG would be. b) [2 marks] Why is it useful to use this form? c) [+2...
