Ther.m.s. velocity of oxygen molecule at 16∘C16^{{}^{\circ}} \mathrm{C} is 474m/sec⁡474 \mathrm{ m} / \mathrm\sec. The r.m.s. velocity in m/s\mathrm{m} / \mathrm{s} of hydrogen molecule at 127∘C127^{{}^{\circ}} \mathrm{C} is

Options

  1. A1603
  2. B1896
  3. C2230.59
  4. D2730

Correct answer

C. 2230.59

Step-by-step solution

voxg⁡.=3R×28932(vrms=3RTM)vH=3R×4002v_{\operatorname{oxg}.}=\sqrt{\frac{3 R \times 289}{32}}\left(v_{\mathrm{rms}}=\sqrt{\frac{3 R T}{\mathrm{M}}}\right)\mathrm{v}_{\mathrm{H}}=\sqrt{\frac{3 \mathrm{R} \times 400}{2}} so vH=2230.59m/sec⁡\mathrm{v}_{\mathrm{H}}=2230.59 \mathrm{ m} / \mathrm\sec
