RMS velocity of oxygen molecules at NTP is \(0.5 \mathrm{~km} / \mathrm{s}\). The RMS velocity for the hydrogen molecule at NTP is
- A \(4 \mathrm{~km} / \mathrm{s}\)
- B \(2 \mathrm{~km} / \mathrm{s}\)
- C \(3 \mathrm{~km} / \mathrm{s}\)
- D \(1 \mathrm{~km} / \mathrm{s}\)
Answer & Solution
Correct Answer
(B) \(2 \mathrm{~km} / \mathrm{s}\)
Step-by-step Solution
Detailed explanation
RMS velocity of molecules at NTP \[ v_{\mathrm{rms}}=\sqrt{\frac{3 R T}{M}} \] RMS velocity of oxygen molecules at NTP \[ \left(v_1\right)=\sqrt{\frac{3 R T}{M_1}}=0.5 \mathrm{~km} / \mathrm{s} \] RMS velocity of hydrogen molecules at NTP…
