R stands for the gas constant and n for moles of gas The parameters a and b must be determined for each gas from experimental data. Use the van der Waals equation to answer the questions in...
Atomic gas which obeys Van der Waals equation of state RT= (P+ a/ V2) (V-b) has internal energy (per mole) of u = 3/2 RT - a/V where 'V' is volume of mole in temperature T. In the beginning, the gas temperature is T1 and volume V1. The gas is let to expand adiabatically so that its final volume is V2. What is the final temperature of the gas?
Use the van der Waals equation of state to calculate the pressure of 2.30 mol of CH, at 455 K in a 5.50 L vessel. Van der Waals constants can be found in the van der Waals constants table. Use the ideal gas equation to calculate the pressure under the same conditions. atm Under these conditions, would you expect CH, or CCI, to deviate more from ideal behavior? Why? OCCI, because it occupies a larger volume and it has greater...
