2. (12 pts List the reference values for AG and Sof each reaction component and calculate AG and As for the reaction. Using AG, and the average of the experimentally determined value for AH in this experiment, report a semi-experimental value for AS (assume standard tem perature). Compare this value to the theoretical value (AS ) and calculate a percent error. What would cause any variance? (You must show your calculations. You can use the left page for extra space.)...
