In the course of work on the kinetics of this solid state reaction, the problem arose of deducing the reaction constant and the activation energy without exact knowledge of the reaction mechanism ...

The data required for determining the activation energy (Ea), pre-exponential factor (Z), rate constant (k), and half-life (t 1/2) is obtained from plotting the natural logarithm of the program rate ...

GCSE; WJEC; Rates of reaction Activation energy [Higher tier only]. Chemical reactions vary in speed. The rate of reaction measures how much product is made in a given time. For reactions to occur ...
