Which statement about reflux setups is NOT correct? The boiling temperature of the solvent overlaps with the optimal temperature of the reaction. The temperature of water entering the condenser must be the same as the reaction temperature. The reaction typically takes place inside a round-bottom flask. Reflux allows the solvent volume to stay the same throughout the reaction.
