Reactions favor lowest activation energy
Web2 Answers Sorted by: 17 Spontaneous reactions simply mean that the products will be lower in free energy than the reactants ( Δ G is negative). If Δ G is negative, then it is energetically favourable for the reaction to occur - in other words, there will be a … 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).

Firstly the substrate binds with the enzyme’s active site and forms a transition state of enzyme-substrate complex. dwans thurlesWebNov 24, 2014 · Polar protic solvents have large dipole moments. They lower the energy of both the transition state and the starting material. But they stabilize the transition state more because it is more polar. This lowers the activation energy, so the reaction goes faster. The dielectric constant of a solvent is a rough measure of the solvent's polarity. dwan of the sevenWebBy lowering the energy of the transition state, which is the rate-limiting step, catalysts reduce the required energy of activation to allow a reaction to proceed and, in the case of a reversible reaction, reach equilibrium more rapidly. dwan stands forWebJul 19, 2024 · If the temperature is higher, the reactant molecules have a higher kinetic energy, and thus the energy difference between the threshold energy and the energy of the molecules will decrease, that is, the activation energy will decrease. physical-chemistry kinetics energy Share Improve this question edited Jul 19, 2024 at 16:37 Mithoron dwan perry lexington kyWebSep 10, 2012 · Here’s one thing we can say with confidence: at low temperatures, the activation energy for the substitution reaction is lower than that for the elimination reaction. Remember that the lower the activation energy, the higher the rate of the reaction. dwans off licenceWebAug 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.
