Igcse Model Questions Vol1 2022 Chemistry Question 25
Practice objective / multiple choice question 25 from the 2022 Igcse Model Questions Vol1 Chemistry examination.
The vapour pressure of solid iodine at 300 K is 0.30 Pa. Its enthalpy of sublimation is 62 kJ mol⁻¹. Using the Clausius-Clapeyron equation \(\ln(P_2/P_1) = -\dfrac{\Delta H_{sub}}{R}\left(\dfrac{1}{T_2}-\dfrac{1}{T_1}\right)\) (with \(R = 8.314\) J mol⁻¹ K⁻¹), estimate the vapour pressure at 350 K. Give your answer to two significant figures.
