Current Attempt in Progress
From the curves shown in Animated Figure and using the following Equation, determine the rate of recrystallization for pure copper
at the several temperatures. Make a plot of In(rate) versus the reciprocal of temperature (in K-1). (a) Determine the activation
energy for this recrystallization process. (See Section FACTORS THAT INFLUENCE DIFFUSION.) (b) By extrapolation, estimate the
length of time required for 50% recrystallization at room temperature, 20°C (293 K).

- C. Pls answer asap . Pls provide accurate answer. Help me thank uuu. Handwritten thank u.arrow_forwardThe "down arrow" on the far left of the toolbar directly above the space for your answer will take you to the subscript "x2" and superscript "x2" options. If you can't make these options work, then write subscripts on the same line and enclose superscripts in parentheses on the same line. For example MnO4(-) would be accepted as MnO4-. Use --> (dash, dash, greater than) for your arrow. Do NOT use the equal sign "=". Write and balance the equation representing what happens when Mg(NO3)2(s), a strong electrolyte, dissolves in water. Include all physical states.arrow_forwardPlease show a clear picture of the spreadsheet /excel file of the data including the equations used in excel.arrow_forward
