Activation energy is a term in the Arrhenius equation used to calculate the energy needed to overcome the transition state from reactants to products. The Eyring equation is another relation that describes the rate of reaction, except instead of using activation energy, it includes Gibbs energy of...
The volume of activation is probably easier to understand on an elementary level than the other important quantities of activation, i.e., the free energy, enthalpy, and entropy. Furthermore, the volume of activation should be rather ... E Whalley - 《Advances in Physical Organic Chemistry》 ...

It is found that the protonation of methane to CH5(+) decreases the energy for subsequent homolytic cleavage resulting in the exothermic (24.1 kcal/mol) formation of CH4(+*). Subsequent reaction with neutral methane while reforming CH5(+) gives the methyl radical enabling reaction with excess ...

Because the O-O bond energy in PS and PMS is smaller than that in H2O2, PS and PMS are easier to be activated [31]. In many previous researches, the UV wavelength for PS/PMS activation was fixed in 254 nm, which was proved indeed to provide enough energy to destroy the –O–O...

Bacterial ClpP is a highly conserved, cylindrical, self-compartmentalizing serine protease required for maintaining cellular proteostasis. Small molecule acyldepsipeptides (ADEPs) and activators of self-compartmentalized proteases 1 (ACP1s) cause dysregu
There is considerable uncertainty about the mechanism by which the β2-adrenergic receptor (β2AR) is activated. Here we use molecular metadynamics computations to predict the mechanism by which an agonist induces the activation of the β2AR and its cogn
