QUESTION 1 Calculate the pressure exerted by Ar for a molar volume 0.39L at 265K using the van der Waals equation of state. The van der Waals parameters a and b for Ar are 1.355 bar dm6 mol-2 and 0.0320 dm³mol-1, respectively. Please write your answer (unit: bar) round to 1 decimal places, as 12.2. Please do not add unit to your answer.
1. The Helmholtz function of a certain gas is given by (V – F (T,V) = –nRT |1+ ln v – nb)T? an? пф V where n is the number of moles of gas, T is the temperatures of the gas, V is the volume of the gas, and a, b, and o are constants. (a) Derive the equation of state, the entropy, and the internal energy of the gas. (b) Suppose that 100 moles of the gas expands from 2 m3 to 5 m³ at 280 K and that the constants have the values a = 0.364 J m3 mol-2, b = 4.27 × 10-5 m³ mol-1, and $ = 1.09 × 10-5 m³ K³/2 mol-1. Calculate: (i) AU. (ii) the maximum energy that can be made available for work due to the process.
