Prepare a Temperature vs Time cooling curve for each of the two trials involving the lauric acid/stearic acid mixtures. Perform a linear regression analysis on the cooling and freezing regions as before. Calculate the point of intersection and identify this point on each graph by inserting a text box and arrow. Report the freezing point for each of the two trials [T(1) and T (2)]. Freezing point (1st trial of lauric acid) T(1) = Freezing point (2nd trial of lauric acid) T/(2) =
