Unformatted text preview: C & 20.0 MPa. In each case, what is the dominant reason for non-ideal behavior? ~Z Reason V (m 3 ) 1. H 2 1.20 size/repulsion 7.28x10-5 . 2. O 2 0.75 attraction 4.55x10-5 . II. Hand-In Problems Due: 2:00 PM, Wednesday February 17, 2010 A. (10 pts) The dominant component of air is N 2 . Explain as completely as you can, why air (i.e. N 2 ) can, to a first approximation can be considered an ideal gas at 25.0 C & 1.00 bar. B. (15 pts) Calculate the volume occupied by 0.654 moles of N 2 (g) at –65.0 C & 10.0 MPa....
