For some transformation having kinetics that obey the Avrami equation (Equation 11.17), the parameter n is known to have a value of 2.3. If, after 145 s, the reaction is 50% complete, how long (total time) will it take the transformation to go to 88% completion

Answer:

t ≈ 235.47 secs

Explanation:

Calculate how long it will take the transformation to go to 88% completion

Given that Avrami equation ( y )= 1 - exp( - kt^n )

n = 2.3

t = 145 secs

reaction = 50%  after t = 145 secs

Reaction = 88%  after t = ?

attached below is a detailed solution
