A mixture of He and CH₄ in a vessel is allowed to effuse out through a small hole at constant temperature. What is the mole fraction of He, if the initial rates of effusion are the same for both gases?
Options:
Answer:
A
Solution:
Rate ∝ xP/√(M). Equal rates: x(He)/√(4) = (1 - x(He))/√(16), i.e., x/2 = (1 - x)/4, so 6x = 2 and x = 1/3 = 0.33. Confirms Ans: (a) 0.33.
