Question:

For some transformation having kinetics that obey the Avrami equation, the parameter n is known to have a value of 1.2. If after 119 s, the reaction is 50% complete how long will it take the transformation to go to 87% completion?

Avrami's equation:

The mathematical relation that describes the information for the transition of solid substances from one phase to another phase is called Avrami's equation. Avrami's equation is used to analyze, as well as to interpret various chemical reactions and laboratory inspections.
