A mixture of ideal gas contains 5 moles of monatomic gas and 1 mole of rigid diatomic gas is initially at pressure P 0 , volume V 0 , and temperature T 0 . If the gas mixture is adiabatically compressed to a volume then the correct statement(s) is /are,

(Given 2 1.2 = 2.3; 2 3.2 = 9.2; R is gas constant)

A
Adiabatic constant of the gas mixture is 1.6
B
The final pressure of the gas mixture after compression is in between 9P 0 and 10P 0
C
The work |W| done during the process is 13RT 0
D
The average kinetic energy of the gas mixture after compression is in between 18RT 0 and 19RT 0 .
