The answer is suppose to be 560 J/mol. i dont understnd how to get this answer.......
I thought when A has 2 mol and B has 1mol mole fraction would be 2/3 for A and 1/3 for B then the result is delta S = -R (3N)*((2/3)ln(2/3) + (1/3)ln(1/3)) (and this was actually the answer of (4)!) but the result is 3Rln(2). Where am i wrong? what is the difference between microstates in 2mol A 1mol B and 2mol A 1mol A ? 1A rigid container is divided into two compartments of equal volume by a...
9 Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. An insulated rigid tank is divided into two compartments by a partition. One compartment contains 9.5 kg of oxygen gas at 40°C and 100 kPa, and the other compartment contains 4 kg of nitrogen gas at 20°C and 150 kPa. Now the partition is removed, and the two gases are allowed to mix N2 4 kg 20℃...
question details in pic. answer please 1. the expansion work in kJ is ? 2. the final temperature of the ideal gas in K is? 3. the change in entropy of the gas during this process in kJ/K is? Problems 18-20 are based on the following description An Insulated rigid tank is divided into two equal parts by a partition. Initially, one part contains 10 kg of an ideal gas with molar mass M-16 kg/kmol, a pressure of 330 kPa,...
please answer 18-20 Question 18 1 pts Problems 18-20 are based on the following description An insulated rigid tank is divided into two equal parts by a partition. Initially, one part contains 10 kg of an ideal gas with molar mass M = 16 kg/kmol, a pressure of 330 kPa and a temperature of 50 oC. The other part is evacuated. The partition is now removed and the gas fills the entire tank (R.- 8.31447 k/MOLK) The expansion work in...
I. (30 pts.) One mole of an ideal gas with constant heat capacities and ? 5/3 is compressed adiabatically in a piston-cylinder device from T1-300 K, pi = 1 bar to p2 = 10 bar at a constant external pressure Pext"- P2 -10 bar. Calculate the final temperature, T2, and W, Q. AU, AH for this process. 2. (20 pts.) Repeat problem 1 for an adiabatic and reversible compression. 3. (20 pts.) A rigid, insulated tank is divided into two...
I just need a reduction in the first law for these three problems, to check my work. Also state your CV for each problem and why. Do not solve the problems. Thank you. 4-23 An ideal gas undergoes two processes in a piston- cylinder device as follows: 1-2 Polytropic compression from T, and P, with a polytropic exponent n and a compression ratio of r = V1/V2. 2-3 Constant pressure expansion at Pa = P, until V=V.
