Question 365: Thermodynamics & KTG

Question

The rms speeds of the molecules of Hydrogen, Oxygen and Carbon dioxide at the same temperature are VH, VO and VC respectively then :

Accepted Answer

$${V_{RMS}} = \sqrt {{{3RT} \over {{M_W}}}} $$
At the same temperature $${V_{RMS}} \propto {1 \over {\sqrt {{M_W}} }}$$
$$\Rightarrow$$ V
H
> V
O
> V
C
Option (a)

Answer

VH > VO > VC

Answer

VC > VO > VH

Answer

VH = VO > VC

Answer

VH = VO = VC
