Ethylene glycol is mixed with water and used as an antifreeze in automobile cooling systems. If a 50% (v/v) solution is made using pure ethylene glycol and pure water, it will have a freezing point of about \(-65^{\circ} \mathrm{C}\). What will happen to the freezing point of the mixture if ethylene
