Question

calculate the root mean square velocity and kinetic energy of CO,CO2, and SO3 at 284K.

Answer #1

The molar gas constant "R", has the value 8.3143 J/mol K,

and the Temperature "T", is in Kelvin.

Since the joule is the kg-m^{2}/s^{2}, the molar
mass must be in kg/mol

v_{rms} = (3RT/M)^1/2,

v_{rms} CO = [(3)(284K)(8.3143 J/mol K) / (0.02801
kg/mol)]^1/2 = **502.89 m/sec**

v_{rms} CO_{2} = [(3)(284K)(8.3143 J/mol K) /
(0.04401 kg/mol)]^1/2 = **401.2 m/sec**

v_{rms} SO_{3} = [(3)(284K)(8.3143 J/mol K) /
(0.08006 kg/mol)]^1/2 = **297.46 m/sec**

K.E. = 1/2 (mass) (velocity)^{2} or

= 3/2 RT Joules/mole

= 1.5 (8.314 J/mol-K)(284K)

= 3542 joules per mole

* 3542 J/mole is the average K.E.* for any
of the three gases
