At what temperature (in kelvin) is the rms speed of hydrogen molecules the same as oxygen molecules at $1327 ℃$ ?

Options:

Answer:

Solution:

${v_{H}}_{2} = {v_{O}}_{2}$

$\sqrt{\frac{3 {R T}_{H}_{2}}{M H_{2}}} = \sqrt{\frac{3 R {T_{O}}_{2}}{M O_{2}}}$

So, $\sqrt{{M_{O}}_{2} {T_{H}}_{2}} = \sqrt{{M_{H}}_{2} {T_{O}}_{2}}$

$32 \times {T_{H}}_{2} = 2 \times 1600$

$T_{H}_{2} = 2 \times \frac{1600}{32} = 100$
