Waec Model Questions Vol1 2020 Chemistry Question 3
Practice objective / multiple choice question 3 from the 2020 Waec Model Questions Vol1 Chemistry examination.
A 2.00 L gas mixture at 298 K and 1.00 atm contains only pentane (C₅H₁₂) and 1‑pentene (C₅H₁₀). The mixture is passed over a nickel catalyst where the alkene is hydrogenated to the corresponding alkane using excess H₂. After the reaction the pressure drops to 0.85 atm (temperature unchanged). Assuming ideal behaviour, determine the mole fraction of 1‑pentene in the original mixture.
