Draw the potential energy diagram an exothermic S_N1 reaction.

Question

Quizplus · Accepted Answer

Exothermic reactions are characterized by a negative ΔH (enthalpy change) value. This means that the products have less energy than the reactants, and energy is released in the form of heat. The potential energy diagram for an exothermic reaction has the reactants at a higher energy level than the products, with a negative ΔH value (energy difference between products and reactants). 
Option B shows an exothermic reaction where the products (P) have lower energy than the reactants (R), with energy being released (ΔH<0) as the reaction proceeds. Options A, C, and D do not meet the criteria for an exothermic reaction as they show reactants with lower energy than the products or have a positive ΔH.
