Calculate the RMS velocity of hydrogen molecule at 0^@C. |
|
Answer» Solution :The RMS velocity (U) is GIVEN by `u=sqrt((3RT)/M)` In the present case, `T=0^@C = 273 K, M = 2, R = 8.31 xx 10^7 "ERGS " K^(-1) MOL^(-1)` `:. ""u= sqrt((3xx8.31 xx 10^7 xx 273)/2) = 1.845 xx 10^5 " cm " s^(-1)` Hence, the RMS velocity of hydrogen molecules at `0^@C " is " 1.845 xx 10^5" cm " s^(-1)`. |
