One mole of a gas is expanded isothermally at 300 Kelvins from 5.00 MegaPascal to 0.10 MegaPascal. If this gas obeys the equation of state given below and from this B is equal to 2.0 x10^4 L/(mol-K^2), answer the question that follow.
Calculate the change in molar Gibbs free energy (in KJ/mole) for this process. Express answer in THREE SIGNIFICANT FIGURES.
2.00 moles of nitrogen gas at 25.0 °C, confined within a cylinder by a piston maintaining a constant pressure of 1.00 atm, is heated with 3.90 kJ of energy. Assume all the energy is used to do work of expansion of the gas at 1.00 atm. What will be the final temperature (in °C) of the gas? Recall ∆H = ∆E + P∆V and watch your units!
1. The equation of state of the actual gas is as follows. v (P+ 10 /v^ 2 )= RT, provided that the units of v and P are m^ 3 /kmol and kPa.
300K, 0.3 kmol of gas in the cylinder expanded from 2m^3 to 5m^3 in an isothermal process. Answer the following questions. (1) What is the unit of the number 10 in the above equation? (2) Find the work done during this process. (3) If the equation for the internal energy of this gas is the same as the internal energy of the ideal gas, find the amount of heat transfer during this process.
