At 133.33 K . the RMS velocity of an ideal gas is ( M 0.083 ~kg ~mol ⁻¹: R =8.3 ~J ~mol ⁻¹ ~K ⁻¹ )
Options
- A200 ~ms ⁻¹
- B150 ~ms ⁻¹
- C2000 ~ms ⁻¹
- D400 ~ms ⁻¹
Correct answer
A. 200 ~ms ⁻¹
Step-by-step solution
Given T =133.33 K M =0.083 ~kg ~mol ⁻¹ R =8.3 ~J ~mol ~K ⁻¹ To Find the RMS velocity of an ideal gas the formula is- v_ rms = 3 RT M putting the value in the formula. v_ rms = 3 8.3 ~J ~mol ⁻¹ ~K ⁻¹ 133.33 k 0.083 ~kg / mol v_ rms = 3323.99 0.083 v_ rms = 40048.14 ~J ~kg ⁻¹ v_ rms =200.12 ~m / s
