CH₄ and He have molar ratio 4:1 in a vessel at 5 atm and 400 K, and escape through a small hole. Select correct statements.
Options:(select one or more)
Answer:
A, D
Solution:
Initial p_CH₄=4 atm and p_He=1 atm. During effusion at fixed volume and temperature into low external pressure, both partial pressures fall toward zero. The CH₄ pressure drop rises from zero toward 4 atm, graph A. Helium pressure does not rise as in B, and pressure drop does not fall as in C. Increasing temperature at fixed volume and amount raises molecular speed and effusion rate, D. Answer A,D.
