Interpretation:
The value of constants n and c for the given equation needs to be calculated.
Concept Introduction:
At constant temperature, the determination of solid phase transformation is done by using the Avarmi equation. Generally, it is used to describe the rate of kinetic crystallization.
This equation is also known as the JMAK equation as it was founded by Johnson-Mehl-Avrami-Kolmology. This equation was first found in the year
Answer to Problem 12.3P
The constant value of
Explanation of Solution
Given:
Eqauation:
Temperature =
Assume:
Elapsed time −
Temperature constants -
From the given equations of curves, the values of f and time are:
Time (min) | |
Table
To calculate the constants value of c and n by using the below formula,
Taking natural logarithm on both sides,
