If all degrees of freedom of a linear N-atomic gaseous molecule are excited (translation, rotation and vibration), then the CP/CV ratio of the gas should be
Options:
Answer:
A
Solution:
A linear molecule has 3 translational, 2 rotational and 3N - 5 vibrational modes. Vibrational modes contribute R each. CV = 3/2R + R + (3N-5)R = (3N-2)R, CP = (3N-1)R. γ = (3N-1)/(3N-2) = 1 + 1/(3N-2). Matches (a).
