Neco 2021 Chemistry Question 38
Practice objective / multiple choice question 38 from the 2021 Neco Chemistry examination.
A 2.00 L rigid container at \(298 \ \text{K}\) initially contains 0.500 mol of hydrogen gas (\(H_{2}\)) and 0.300 mol of oxygen gas (\(O_{2}\)). The mixture is ignited, and the reaction proceeds to completion according to \(2 H_{2} + O_{2} \rightarrow 2 H_{2}O(g)\). Assuming ideal‑gas behaviour and that the temperature remains at \(298 \ \text{K}\) throughout, calculate the final pressure in the container after the reaction. Give your answer in atmospheres to two decimal places.
