Question : How would the product ratio of the reversible reaction shown below change with the type of acid used in the reaction ?

1. Please explain whether you would anticipate problems for the outcome of our reaction if you were to change the procedure by
2. a) using 9M phosphoric acid instead of 9M sulfuric acid,
3. b) letting the reaction proceed for 5 hours instead of 45 minutes.
