3. The following data have been obtained experimentally for the time required to completely recrystallize copper at various temperatures: T (K) Time (s) 316 2,300,000 361 33,000 375 10,000 385 7,000 392 4,000 408 1,500 a. Fit these data to a rate equation of the form Rate = A exp (-Q/RT), (A and Q are coefficients to be determined), where the rate is the inverse of a specific time in a transformation process (here, the specific time is the time required for complete recrystallization).

b. Using your results, determine the recrystallization temperature (temperature at which complete recrystallization takes one hour) for copper.

c. Using your results, determine how long complete recrystallization of copper take at room temperature (assume room temperature is 25 C)?
