The backward-forward asymmetry of the reaction was investigated via the direct detection of neutrons scattered at the laboratory angle of 15 degrees and 165 degrees from a polyethylene sample enriched with deuterium. In order to extend the measurement to neutron energies below 1 MeV, Li-6 glass ...
英文: If an arm is stretched forward under water resistance is increased and a reaction force backward is developed, both of which would contribute to negative acceleration.中文: 如果手臂在水中是向前伸展则阻力会随之增加而向后方的反作用力也会出现,二者都会产生负加速度。

Ef=Activation energy of forward reaction Eb=Activation energy of backward reaction ΔH=Ef−Eb Ef=threshold energy The activation eneries for forward and backward reactions in a chemical reaction are30.5and45.4kJmol−1respectively. The reaction is ...
To solve the problem, we need to analyze the relationship between activation energy, enthalpy change, and internal energy change in a chemical reaction. Here’s a step-by-step breakdown:Step 1: Understand Activation Energy Acti
backward - directed or facing toward the back or rear; "a backward view" 2. forward - used of temperament or behavior; lacking restraint or modesty; "a forward child badly in need of discipline" bold - fearless and daring; "bold settlers on some foreign shore"; "a bold speech"; "a ...
A rigorous rule which forbids forward and backward scattering is established for a certain class of inelastic collisions. The rule depends only on conservation of angular momentum and parity, and is therefore true, independent of the interaction and of the mechanism of the reaction. The class of ...

To find the activation energy for the backward reaction, we can use the relationship between the activation energies of the forward and backward reactions and the change in enthalpy (ΔH) of the reaction.1. Identify Given Values
