Chemistry - Ideal Gas Question with Solution | TestHub
Gases in Column I effuse through the same small hole at the same temperature and pressure. Match each pair (first gas : second gas) with the statements in Column II that are true (a Column I entry may match more than one Column II entry):
Column I (Pair of gases) | Column II (Statement) |
|---|---|
() : (D = 2 u) | (1) the first gas effuses faster |
(Q) : | (2) ratio of rates = 2 : 1 |
() : | (3) for equal moles, the time ratio (first : second) is 1 : 2 |
(S) : | (4) ratio of rates = : 1 |
| (5) the first gas effuses slower |
Choose the option with the correct matching:
Options:
Answer:
Solution:
Rate is proportional to 1/, so rate ratio (first : second) = and time ratio = .
() = : 1. The lighter is faster: 1, 4.
(Q) = 2 : 1. is faster, and the time ratio is = 1 : 2: 1, 2, 3.
() = 1 : 2. is slower: 5.
(S) = 1.22 : 1. is faster, and the ratio is not listed: 1.
Correct matching: to 1,4; Q to 1,2,3; to 5; S to 1. Answer: ().
