Question

Methane (CH) has a boiling point of "Cat 10 atm and a vapor presure of 42.8.am at -100."C. Which of the following options correctly reflect the calculations needed to determine the value of AP for mathem? Select all that apply. Check that apply GRA- 42 105 mol G. 100 m wa

Answer 1

Given, Tintial temperature, T = -1640 – – 164+ 273k = 109K Initial Vapor pressure, P,= 1:0 aton. Final temperature, T₂ = – 100 c- - 100+ 273k = 173k Final Vapor precual, P = 42.8 atm waite the equation of Churins Clapeyren as follows: enco) - Shine lt > The required calculations are as follows: tot 172-ta = -0.00339 k' en (22) = leu (42.8 3.756 ① and Cros Contact R = 8.314 J/molk substitute the conceporling values in Equation Calculate Strap- 3.756 = -Attrop - (-0.00339 k-1) 8.314 J/molk Athrop - 8007 J/mol | Attrap = 8.00 kJ/mol
