B
If all the molecules dissociate into atoms, internal energy of gas sample decreases (assuming same temperature)
C
If all the molecules dissociate into atoms, internal energy of gas sample increases (assuming same temperature)
D
Internal energy of gas sample will remain unchanged and unaffected due to dissociation (assuming same temperature)
