Question

Question: Draw an energy diagram for a reaction in which the products are higher in energy than the starting materials and ${\mathbf{E}}_{\mathbf{a}}$is large. Clearly label all of the following on the diagram: the axes, the starting materials, the products, the transition state, $\mathbf{∆}{\mathbf{H}}^{\mathbf{°}}$,and ${\mathbf{E}}_{\mathbf{a}}$.

Short answer

Answer

Step-by-step solution

Step-by-Step SolutionsStep 1: Activation energy

The energy barrier between the reactants and the products of a reaction is termed the activation energy i.e., it is the energy to be overcome by the reactants to turn into products.

Change in enthalpy (∆H°)

The energy difference between the products and the reactants of a reaction yields the change in enthalpy of the reaction.

Energy diagram

The plot of energy vs the reaction coordinate for a reaction gives the energy profile diagram of a chemical reaction.
