WebMar 23, 2024 · This pathway actually provides less activation energy barrier for the substrate molecules so that more molecules take part in reaction and thus the rate of reaction increases. Firstly the substrate binds with the enzyme’s active site and forms a transition state of enzyme-substrate complex. WebThe conditions of the reaction, such as temperature, pressure, or solvent, affect which reaction pathway may be favored: either the kinetically controlled or the thermodynamically controlled one. Note this is only true if the activation energy of the two pathways differ, with one pathway having a lower Ea ( energy of activation) than the other.

WebSep 3, 2024 · The transition state for the endo product (C) is lower in energy than the transition state for the exo product (B), meaning that it is formed faster ( i.e. has a lower activation energy) At low temperatures, the forward reaction to make the endo is accessible (A→C→D) but not the reverse reaction (D→C→A). WebAug 11, 2015 · The more elimination products you get, since the amount of reactant is limited, the less substitution products you get, as well. This is because the activation energy for a particular reaction with particular reactants is higher for elimination reactions than for substitution reactions of those same reactants. Why is that?

WebActivation energy depends on two factors. 1. Nature of Reactants In the case of ionic reactant, the value of (E a) will be low because there is an attraction between reacting species. While in the case of covalent reactant the value of E a will be high because energy is required to break the older bonds. Also Read: Chemical Kinetics 2.
