Three flasks A, B and C have equal volumes. A is maintained at 300 K, B at 600 K and C at 900 K. Flask A contain H2 gas, flask B contain CH4 gas and flask C contain O2 gas, and masses of all gases are same. Assume ideal behaviour of gases.
Flask with greater collision number of the molecules
Options:
Answer:
A
Solution:
Collision number Z11 = 1/(√(2))π d2 barc (N/V)2 ∝ r2 barc n2. Using barc ∝ √(T/M) (√(150), √(37.5), √(28.1)) and r2 = 1, 4, 4: A: 1 × 12.25 × (0.5)2 = 3.06; B: 4 × 6.12 × (0.0625)2 = 0.0957; C: 4 × 5.30 × (0.03125)2 = 0.0207. Flask A is greatest. Hence Ans (a).
