1b. Use the equipartition theorem to calculate the molar specific heat for hydrogen (in gas state).

---

**Attempt at solution:**

1a.

# traslational degrees of freedom (d.o.f.) is 3 for CO2, 3 for CH4.

# rotational d.o.f. for CO2 (linear) is 2, for CH4 (nonlinear) 3

# vibrational d.o.f. for CO2 (linear) is 3N - 5 = 3(3) - 5 = 4, for CH4 (nonlinear) is 3N - 6 = 3(5) - 6 = 9

Is this correct? Do you then add them all up or multiply them or something? What does this all mean exactly?

1b.

Equipartition theorem => Cv = 5R/2

?

I really have no idea how to do this one... How do you apply the theorem here?
