List the reference values for AGr and S° of each reaction component and calculate AG
and ASteoretical for the reaction. Using AG 0g and the average of the experimentally determined
2.
value for AH in this experiment, report semi-experimental value for AS (assume standard
temperature). Compare this value to the theoretical value (AStreoretical) and calculate a percent
error. What would cause any variance? (You must show your calculations.)
