Filling chips packets with nitrogen gas reduces which chemical problem?

Answer and explanation

Correct answer: Oxidation of oil (rancidity)

Chips contain oil or fat. On exposure to oxygen in air, the oil can undergo oxidation and become rancid. Nitrogen is relatively unreactive and reduces the amount of oxygen in the packet, so oxidation of the oil slows down. Evaporation of oil is a different physical process, not the main chemical problem prevented by nitrogen.
