Calculate the rms (average) speed of PH3 atoms or molecules at 123 oC. Use R = 8.314 kg-m2/K-s2-mol for the value of the gas constant.
a) The average speed of a PH3 atom/molecule at 123 oC is 539 m/s.
b) The average speed of a PH3 atom/molecule at 123 oC is 245 m/s.
c) The average speed of a PH3 atom/molecule at 123 oC is 9.50 m/s.
d) The average speed of a PH3 atom/molecule at 123 oC is 291 m/s.
e) The average speed of a PH3 atom/molecule at 123 oC is 17.0 m/s.
