We’re being asked which of the options will the atoms be moving fastest.
To know that we have to calculate for the root mean square speed (μrms) and use the following equation:
µrms = rms speed,
R = 8.314 J/(mol·K)
T = temperature, K
M = molar mass, kg/mol
At which set of conditions listed below will the atoms be moving the fastest?
(a) Ne at 100°C
(b) Ar at 100°C
(c) Ne at 50°C
(d) Ar at 50°C
(e) the conditions in answers (a) and (b) and (c) and (d) will be the same speeds
