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 number of collisions with the walls per unit area per unit time
Options:
Answer:
A
Solution:
Wall collision rate per unit area = 1/4(N/V)barc. With equal volumes, N/V ∝ n ∝ 1/M and barc ∝ √(T/M). Comparing (1/M)√(T/M): A: (1/2)√(300/2) = 6.12; B: (1/16)√(600/16) = 0.383; C: (1/32)√(900/32) = 0.166. Flask A is greatest. Hence Ans (a).
