If for two gases of molecular weights MA and MB at temperature TA and TB, TA MB = TB MA, then which — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

from ta × mb = tb × ma, we get ta / ma = tb / mb. since rms speed is u_rms = √(3rt/m), and the ratio t/m is equal for both gases, their rms speeds must be identical.
