The rms velocity of oxygen molecules of 27^ C is around 800 ~m / s . The rms velocity of methane molecule at 600 ~K temperature is around ......
Options
- A400 ~m / s
- B1600 ~m / s
- C800 ~m / s
- D1200 ~m / s
Correct answer
B. 1600 ~m / s
Step-by-step solution
v_ rms = 3 R T M Let the rms velocity of methane molecule at 600 ~K be x . aligned v_ mss ( O ₂ ) v_ ms ( CH ₄ ) & = 800 x = 3 R(300 ~K ) 32 3 R(600 ~K ) 16 & = 800 x = 300 32 16 600 800 x & = 1 2 x & =1600 ~m / s aligned Hence, the correct option is (2).
