Question: 25 pol QUESTION 1 Assignment 1. Of the two unimolecular reactions shown, decide which you think would be faster, i.e., which would have a higher relative rate constant (kret). 2. Based on your answer, draw two lines on one reaction coordinate diagram that show the relative progress of each reaction along its path to product indicated. 3. positions of atoms during a reaction. Reaction coordinate Energy Energy Diagrams 6 • Transition state ‡: - An unstable species of maximum energy formed during the course of a reaction. - A maximum on an energy diagram. • Activation Energy, ∆G‡: The difference in Gibbs free energy between reactants and a transition state. In an energy diagram, the vertical axis represents the overall energy of the reactants, while the horizontal axis is the 'reaction coordinate', tracing from left to right the progress of the reaction from starting compounds to final products. The energy diagram for a typical one-step reaction might look like this: Reaction coordinate diagrams. The intrinsic reaction coordinate (IRC), derived from the potential energy surface, is a parametric curve that connects two energy minima in the direction that traverses the minimum energy barrier (or shallowest ascent) passing through one or more saddle point(s). However, in reality if reacting species attains enough energy it may deviate from the IRC to some extent.

A general Reaction Coordinate Diagram relating the energy of a system to its geometry along one possible reaction pathway is given in the figure below. In the figure below, the Activation Energy, Ea is that critical minimum energy in a chemical reaction required by reactants to be converted into products. the quantities, Ea; General structure of a reaction coordinate diagram, including transition states and intermediates. Overall free energy change and activation energy. Definiti... The activation energy is the difference between the energy of the starting reagents and the transition state—a maximum on the reaction coordinate diagram. The reagents are at 6 kJ and the transition state is at 20 kJ, so the activation energy can be calculated as follows: A reaction coordinate energy diagram for a substitution process could then be graphed over two different reaction coordinates: breaking the R-X bond and forming the R-Nu bond. For ease of two dimensional representation, these are often presented as contour diagrams.

The fully filled in reaction coordinate diagram is displayed below. The arrow marked in the question represents the activation energy, which is the energy barrier that must be overcome in order for the reactants to form products. This reaction is also exothermic because the energy of the products is lower than that of the reactants.

Reactivity: how fast is the reaction! (how large is the E a in the energy diagram)! Selectivity: if more than one site is available for reaction the ratio between each product obtained determines the selectivity! (the difference in E a for each competing path in the energy diagram)! This leads to an almost universal statement in organic chemistry:!

Typically, we envision reactions proceeding left to right along the reaction coordinate, so often, the activation energy is only noted for the forward reaction. The activation energy on the diagram below shows the barrier to be 102.6 kJ mol-1. Barriers are measured in energy per mole (typically kJ mol-1).
