The terms reaction rate, chemical kinetics, and effective collisions are defined. Reaction Rates: The terms reaction rate, chemical kinetics, and effective collisions are defined. Students learn the ...

A research team from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) has directly measured the masses of two highly unstable atomic nuclei, phosphorus-26 and sulfur-27.

Discusses the factors influencing chemical reaction rates and equilibrium. It explains how different reactions occur at varying rates due to factors such as the nature of reactants, surface area, ...

Rate is most often calculated using the equation: rate = \( \frac {1}{time}\) where the time is the time for the reaction to reach a certain point or the time for the reaction to be completed. The ...
