For some metal alloy it is known that the kinetics of recrystallization obey the avrami equation, and that the value of k in the exponential is 2.70 x 10-6, for time in seconds. if, at some temperature, the rate of recrystallization is 0.0012 s-1, what total time (in s) is required for the recrystallization reaction to go to 90% completion
