Further, when heated with concentrated H2SO4 , the 1- acid is converted into the 2-acid. Kinetic - how unwillingly something reacts. But for questions such as : Under physiological conditions, peptide bond formation and degradation both require enzymes, but only formation requires coupling to GTP hydrolysis. These are the thermodynamically stable isotropic system in which two immiscible liquids are mixed to form a single phase by means of an emulsifying agent, i.e., surfactant and co-surfactant. Also ,since 2-acid is the is thermodynamically controlled product, H2 > H1 . Basically, thermodynamics focuses on whether or not the reaction can occur on its own without any outside force (spontaneous), while kinetics focuses on how fast a reaction occurs (rate).

Kinetics refers to how fast a reaction occurs, and thermodynamics refers to the likelihood of a reaction occurring based on its spontaneity. Targeting G-quadruplexes to achieve antiviral activity. Favorable reactions The reactions that do not require energy to be carried out are called thermodynamically favored reaction. While it's true that thermodynamic stability is the ultimate arbiter of the spontaneity of a reaction, if the kinetics render the reaction too slow then, in practice, the reaction may not actually occur at all (under some given set of conditions).
