Kinetics vs. Thermo Controlling Rxn

[Maria George 3K]

Overall, what does it mean when kinetics controls a reaction vs thermodynamics controlling a reaction?

[Maegan Abutin 2C]

Hi!

When kinetics controls a reaction, the rate of the reaction is the main factor in determining its progress. When thermodynamics controls a reaction, the overall energy changes determines whether the reaction is energetically favorable.

thermodynamics just focuses on initial and final, while kinetics looks at the pathway like how fast it'll happen.

[Sarah Egan 3A]

Kinetics controls reaction rate, focusing on speed and factors affecting it. Thermodynamics controls reaction direction, focusing on stability and spontaneity. Both are important and both can be considered in one reaction.

[Averie Moore 2F]

Kinetics focuses on the rate and mechanism of the reaction while thermodynamics focuses on the energy changes and favorability of a reaction.

[Sophia Lim 2A]

When kinetics control a reaction, the rate of the reaction is the key factor influencing the outcome, while in thermodynamics control, the stability of the products relative to the reactants determines the final composition.

When kinetics controls a reaction, it means that the rate at which the reaction proceeds is determined by the speed at which reactants form products. Factors such as activation energy, reaction mechanisms, and the presence of catalysts influence the rate of the reaction. Kinetic control is often associated with reactions that occur rapidly but may not be energetically favorable. On the other hand, when thermodynamics controls a reaction, it means that the direction of the reaction is determined by the overall energy changes and the stability of the products and reactants. Thermodynamically controlled reactions are driven by the difference in free energy between the reactants and products. Factors such as enthalpy, entropy, and Gibbs free energy changes influence the direction and spontaneity of the reaction. Thermodynamic control is often associated with reactions that are energetically favorable but may proceed slowly due to high activation barriers or complex reaction mechanisms.
