Homework Statement
Consider a sample containing 2.35 mol of an ideal diatomic gas.
(a) Assuming the molecules rotate but do not vibrate, find the total heat capacity of the sample at constant volume.
nCv.=
(b) Assuming the molecules rotate but do not vibrate, find the total heat capacity of the sample at constant pressure.
nCp=
(c) Assuming the molecules both rotate and vibrate, find the total heat capacity of the sample at constant volume.
nCv=
d) Assuming the molecules both rotate and vibrate, find the total heat capacity of the sample at constant pressure.
nCp=
Homework Equations
The Attempt at a Solution
Since diatomic f= 5 when not considering vibration.
so for part a)
nCv= 2.35(5/2)(8.314)=48.9
b)
nCp=2.35((5/2)(8.314)+8.314)=68.4
c) Since Vibrating f=6
nCv=2.35(3)(8.314)=58.6
d)
nCp= 2.35((3)(8.314)+8.314)=78.2
Is this correct, please let me know If I have made a mistake?
Thanks!
