Question

A triatomic non linear gas is expanded by a process following the equation $PV^{2} =$ Constant at a very high temperature. What is the molar heat capacity of the gas in cal/mol for the given process (R = 2 cal/mol-K) [Assume vibrational degrees of freedom to be active]

Options:

Answer:

C

Solution:

$C_{m} = C_{V, m} + \frac{R}{1 - X}$
$= 6 R + \frac{R}{1 - 2} = 5 R = 5 \times 2 = 10 cal / mol$
