From the curves shown in Animated Figure a cλ and using the following Equation 10.18c7, determine the rate of recrystallization for pure copper at the several temperatures. Make a plot of ln (rate) versus the reciprocal of temperature (in K−1 ). (a) Determine the activation energy for this recrystallization process. (See Section 5.5 FACTORS THAT INFLUENCE DIFFUSION 주.) (b) By extrapolation, estimate the length of time required for 50% recrystallization at room temperature, 20∘C(293 K). Figure a (10.18) a) 105.15 kJ/mol, b) 250 days a) 105.15 kJ/mol, b) 360 days a) 94.15 kJ/mol, b) 250 days a) 94.15 kJ/mol, b) 360 days
