Calculate the RMS, average and most probable velocity of SO_2 at 27^@C. |
|
Answer» Solution :Absolute temperature = T = 300 K Gram MOLECULAR weight = M = 64 g `mol^(-1)` Gas CONSTANT `= R = 8.314 xx 10^7 ERG k^(-1)mol^(-1)` RMS velocity (C) = ` sqrt((3RT)/(M)) = sqrt(( 3 xx 8.314 xx 300 xx 10^7 )/( 64 )) = 3.42 xx 10^4cm s^(-1)` `=342 ms^(-1)` Most probable velocity `(C_p) = 0.8166 xx C ` `= 0.8166 xx 342 = 279.27ms^(-1)` Average vclocity `= vecC - 0.9213 XXC -0.9213 xx 342` `= 315 ms^(-1)` |
