A mixture of CH4 and HBr, in a vessel are allowed to effuse out through a small hole at the same temperature. What is the mole fraction of CH4, if the initial rates of effusion are the same for both gases?
Options:
Answer:
A
Solution:
Rate ∝ p/√(M) = xP/√(M). Equal rates: x(CH4)/√(16) = (1 - x(CH4))/√(81), i.e., x/4 = (1 - x)/9, so 13x = 4 and x = 4/13 = 0.31. Confirms Ans: (a) 0.31.
