Question Completion Status: QUESTION 5 Reaction coordinates describe the chemical pathway of a reaction. They indicate thermodynamic favorability, equilibrium distribution of reactants and products, and relative rates at which reactions proceed. Evaluate the following reaction coordinates and rank them according to the properties of the reaction. Assume equivalence of Y axes for the two different curves. k1 reaction S P k-1 ighest/most positive [P]/IS] at equilibrium change in free energy (40) activation energy for forward rxn rate constant (k) for forward rxn

Answer 1

1. P/S is most positive in B because reaction is highly favoured in the product side direction because its final energy is lower than initial energy.

2. Change in free energy is most positive in A because here we see that the energy of product is higher than the energy of reactant. So the difference between final and initial energy will be positive.

3. High steap in graph A reflect that high activation energy is needed in A compare than B.

4. Rate constant has inverse relation with activation energy . Since activation energy of B is lower so rate constant will ne higher so rate constant of B will be most positive.
