WebIn this equation, R is the ideal gas constant, which has a value 8.314 J/mol/K, T is temperature on the Kelvin scale, Ea is the activation energy in joules per mole, e is the constant 2.7183, and A is a constant called the frequency factor, which is related to the frequency of collisions and the orientation of the reacting molecules. WebChemical cracking is the process of breaking down large molecules into smaller, more useful ones. It is a type of thermal decomposition reaction. The term cracking is most commonly used to describe the breakdown of long-chain hydrocarbon fractions from crude oil into shorter-chain alkanes and alkenes.
