Problem: 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

FREE Expert Solution

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 (μrmsand use the following equation:

μrms = 3RTM

µrms = rms speed,
R = 8.314 J/(mol·K)
T = temperature, K
M = molar mass, kg/mol
