Igcse Model Questions Vol1 2024 Chemistry Question 38
Practice objective / multiple choice question 38 from the 2024 Igcse Model Questions Vol1 Chemistry examination.
For substance X the vapour pressure at 350 K is 0.40 atm and at 370 K it is 0.80 atm. Assuming the enthalpy of vapourisation is constant over this temperature range, use the Clausius-Clapeyron equation \(\ln(P_2/P_1)= -\Delta H_{vap}/R\,(1/T_2-1/T_1)\) to calculate \(\Delta H_{vap}\) in kJ mol⁻¹.
