Reaction profile endothermic reaction
WebIn step 1, the C—Br bond breaks and Br departs with the bonding electron pair to produce a tertiary carbocation and bromide anion Br –.This step only involves a highly endothermic bond-breaking process, and this is the slowest step in the whole mechanism. In the multiple-step mechanism, the overall reaction rate is determined by the slowest step, and such a … WebJun 19, 2024 · An endothermic reaction is a non-spontaneous reaction but it will become spontaneous when the following conditions are applied: If energy is changed, enthalpy changes which give the -ve value of Gibbs free energy. Also, spontaneity in a reaction is enhanced if a change in enthalpy causes an increase in entropy.
Reaction profile endothermic reaction

WebThe energy profile for a multistep reaction can be used to compare the activation energies of the different steps and identify the rate-determining step. The energy profile can also … WebMar 13, 2024 · For a endothermic reaction, the products will have a higher overall energy than the reactants. Since the profile is the same, the products staring at a higher energy will mean that less energy is needed to be put in to reach the transition state. Thus, the activation energy will be less for the reverse reaction of an endothermic reaction.
