Energy Diagram_ Chemistry

Question

Hello! I need to draw an energy diagram but I am mildly confused as to how to go about it.

The diagram below shows steps in the exothermic chemical reaction of bromomethane with hydroxide to form methanol and bromide ion. The black spheres are carbon atoms, the white spheres are hydrogen atoms, the red spheres are oxygen atoms, and the blue dots are bromine atoms.

A is the reactant, C is the transition state and B is the product.

Draw an energy diagram of the reaction in which you label the energies of each step in the reaction and the activation energy.

Answer 1

Answer 2

An energy diagram shows the amount of energy in a system over time. When you're asked to draw an energy diagram, the format is usually the same depending on the kind of reaction (exothermic or endothermic). Here is the general format for this kind of question: https://imgur.com/7nx1f5a. The reactant(s) are usually the beginning (A). Then to start a reaction, activation energy must be added to reach the transition state (B). In an exothermic reaction, energy is released and exits the system, so for the products, the line goes down below the energy of the reactants (C).
