At what temperature will the molar kinetic energy of 0.3 mol of He be the same as that of 0.4 mol of argon at 400 K ?

Question

At what temperature will the molar kinetic energy of 0.3 mol of He be the same as that of 0.4 mol of argon at 400 K ? (A) 700 K (B) 500 K (C) 800 K (D) 400 K

Tardigrade Admin · Accepted Answer

Molar Kinetic energy of a gas depends upon the temperature. At constant temperature, kinetic energy of all gas molecules is same. So molar kinetic energy of 0.3 mole of He will be same as the molar kinetic energy of 0.4 mole of argon at 400 K.
