For the following acid-base reaction, predict the position of the equilibrium and identify the most acidic compound.

◦ favor the left side with compound III being the most acidic compound
◦ favor the right side with compound III being the most acidic compound
◦ The reaction is at equilibrium so all the compounds are in equal concentration
◦ favor the left side with compound I being the most acidic compound
◦ favor the right side with compound I being the most acidic compound
