Question

Calculate the isochore molar heat capacity of a distiomkc has knowing the molecules mean square velocity of Vr=600m/s at T=27C

Answer 1

Therefore the isochore polar heat capacity of a diatomic is 20. 785 J/mol K

Step-by-step explanation:

Solution

Recall that:

Vr = 600 m/s

T = 27°C

The molar heat capacity at constant volume is given below:

Cv = R/r -1

Here

r = 1 +2/f

For diatomic f = 5

Thus

r =1 +2/f =7/5

v =R/7/5 - 1

=5R/2 =5/2 * 8.314 J/mol K

Hence Cv = 20. 785 J/mol K
