Answer: x = -7/2
Step-by-step explanation:
10x+ 30 = 20 +8x+ 3
10x+ 30=23+8x
10x-8x = 23-30
2x=-7

Given Information:
constant = n = 1.7
transformation time 50% completion = t₅₀ = 100 s
Required Information:
transformation time 99% completion = t₉₀ = ?
Answer:
transformation time 99% completion =

Step-by-step explanation:
The Avrami equation is used to model the transformation of solids that is from one phase to another provided that temperature is constant.
The equation is given by

Where t is the transformation time in seconds and n, k are constants.
Let us first find the constant k, since after 100 s transformation is 50% complete,




Take ln on both sides,





Now we can find out the time when the transformation is 99% complete.




Take ln on both sides,




Again take ln on both sides





Take exponential on both sides
