Questions
A gas mixture consists of 2 moles of oxygen and 4 moles of argon at temperature ‘T’. Neglecting all vibrational mode, the total internal energy of the system is
detailed solution
Correct option is D
Total Internal Energy of System =Uoxygen+Uargon=μf12RT+μ2f22RT(f= degree of fredom )=252RT+432RT=5RT+6RT=11RTAs f1=5for oxygen and f2=3for ArgonTherefore, the correct answer is (D).Talk to our academic expert!
