Choose the INCORRECT statement about coupled reactions.
◦ The usual practice of coupling reactions is to join two nonspontaneous reactions.
◦ The usual reason to couple reactions is to produce an overall spontaneous reaction.
◦ The reaction added to a nonspontaneous reaction needs to be spontaneous.
◦ The reaction added to a nonspontaneous reaction needs to be more spontaneous than the original reaction is nonspontaneous.
◦ One of the coupled reactions has a negative ΔG, the other a positive ΔG.
