###### Question:

The reaction of MnO4 with oxalic acid (H2C204) in acidic solution, yielding Mn2+ and CO2 gas, is widely used to determine the concentration of permanganate solutions. a. Write a balanced equation for the reaction. b. Show that the reaction goes to completion by calculating the values of AGº and K at 25 °C. Most values for AG°f are in the back of your textbook. AG°f of H2C2O4(aq) is -674.0 kJ/mol. If your calculator will not give you an actual value of K, just use the exponential expression (e). Again, provide some reasoning for what you are doing.
