Answer the following parts
Part A. Once you have obtained the electrostatic potential value
for your unknown acid, use the plot you obtained for the known
carboxylic acids to obtain the pK, value for your unknown acid. Do
not "eyeball" the pK, value on the graph. Rather, using your
trendline to calculate the value will be a more accurate
determination. Show your calculation in the space below
