Question

Kinetic Molecular Theory of Gases What is the root mean square (rms) velocity of the CO2 molecule at 312 K? 1pts Submit Answer Tries 0/5 What is the most probable velocity of the NH3 molecule at 323 K? 1 pts Submit Answer Tries 0/5

Answer 1

Root mean square velocity (R..S) - Where R= gas constant : 8.314 J K med T = Temperature in Keluin M = Molar mass in Kolmole Molar mass of CO₂ = 0.044 kg/mole Temperature = 312k Pubstituting values in the above yormula Ums= 312 3x 8-314 0.044 - 1781.904 V 0.044 Urms = 420.54 m/see Most probable velocity = V2RT Molar mass of NH₃ = 17 glmol = 0.017 Kylmole Temperature = 323k 0.7748 344 323 = 562 m/sec 0.017 Most probable velocity of Ally = 562 m/sw.
