Gce Model Questions Vol1 2024 Chemistry Question 6
Practice essay / theory question 6 from the 2024 Gce Model Questions Vol1 Chemistry examination. This question covers States of Matter .
A sealed rigid container of volume 5.00 L contains 0.80 mol of nitrogen gas (N₂) at 298 K. The container is then heated to 350 K. (a) Calculate the final pressure of the gas, assuming ideal behaviour. (b) Using the van der Waals constants for N₂ (a = 1.39 L²·atm·mol⁻², b = 0.0391 L·mol⁻¹), calculate the corrected pressure at 350 K. (c) Explain, with reference to intermolecular forces and molecular volume, why the real pressure differs from the ideal pressure. (d) Sketch a qualitative P–T phase diagram for nitrogen, indicating the positions of the initial and final states and the critical point.
