We’re being asked to calculate for the root mean square speed of CH4 at 78°C.
When calculating for root mean square speed (μrms), we will use the following equation:
µrms = rms speed,
R = 8.314 J/(mol·K)
T = temperature, K
M = molar mass, kg/mol
Calculate the root-mean-square speed of methane, CH4 (g), at 78 °C.
(a) 23 m/s
(b) 350 m/s
(c) 550 m/s
(d) 667 m/s
(e) 739 m/s
