What is the activation energy for the reaction in this energy diagram?

The easiest nuclear reaction, at the lowest energy, is D+T: 2 1 D + 3 1 T → 4 2 He (3.5 MeV) + 1 0 n (14.1 MeV) This reaction is common in research, industrial and military applications, usually as a neutron source. Deuterium is a naturally occurring isotope of hydrogen and is commonly available.

Jul 12, 2015 — For a forward reaction, the activation energy is equal to the difference between the threshold energy and the energy level of the reactants.1 answer · Simply put, by drawing a double arrowhead line.

The rule states that for a given electron configuration, the lowest energy term is the one with the greatest value of spin multiplicity. This implies that if two or more orbitals of equal energy are available, electrons will occupy them singly before filling them in pairs. The rule, discovered by Friedrich Hund in 1925, is of important use in ...

Activation energy and pre-exponential factors are calculated from Arrhenius plots using the values of rate constants derived using the proposed model. It was established that the excess amount of oxidant in the reaction mixture leads to over-oxidation products, which was not captured experimentally.

Activation energy - wikipedia

The apparent activation energy was calculated as 16.61 ± 0.99 kJ mol-1. Kinetic parameters such as the diffusion coefficient D, electron transfer number and the transfer coefficients β at 298 K were 8.24 × 10-7 cm2/s, 0.91 and 0.449 separately. The electrochemical reaction was a single electron process.

• From the reaction coordinate diagram, we conclude that the activation energy for endothermic is high due to which it needs heat from external sources. Activation energy is the energy required by reactants to proceed with the reaction and form a transition state. The maxima in the curves represent the transition state.
