Then the proportion of each olefin unoxidized was found by boiling out the gases and analyzing them. Here again isobutene reacted faster than ethylene. Calculations of the relative rates of reaction based on a formula developed by Francis, Hill, and Johnston are given.doi:10.1016/S1062-2888(...

Their formula for the reaction-rate is remarkable because it is a very simple function of the mean compartmental substrate concentration alone, even if the process effects a non-zero variance. This is probably due to the Poissonian nature of the input process in their model. Already in the ...
It is postulated that the usual activation energy in chemical kinetic theory is associated with a threshold magnitude of momentum transfer. On the basis of this, the collision theory for reaction rates, which provides the Arrhenius formula for hard sphere interactions, is generalized to be independen...

The exact reaction rates of beta processes for all particles at arbitrary degeneracy are derived, and an analytic beta-equilibrium condition $\\mu_n=\\mu_p+2\\mu_e$ for the hot electron-positron plasma with nucleons is found, if the matter is transparent to neutrinos. This simple analytic...
