WebBohr's Calculation of the Electron's Energy: Bohr could calculate the total energy of the electron, again using classical mechanics. The total energy of a system is the sum of the kinetic energy (KE, energy of motion of the electron) and the potential energy (PE, from the electrostatic attraction, Fe and the distance, r). KE = 1 2mev2. WebThe Bohr effect (Riggs, 1988) describes the change (Δ) in Hb–O2 affinity that results from a change in H+ concentration and is often expressed numerically as ΔlogP50/ΔpH (Bohr …
