Three flasks A, B and C have equal volumes. A is maintained at 900 K, B at 300 K and C at 600 K. Flask A contains CH₄ gas, flask B contains O₂ gas and flask C contains H₂ gas, and the masses of all gases are the same. Assume ideal behaviour of gases.
Flask with greater number of collisions with the walls per unit area per unit time
Options:
Answer:
C
Solution:
Wall collision rate per unit area = 1/4(N/V)barc. With equal volumes, N/V ∝ 1/M and barc ∝ √(T/M). Comparing (1/M)√(T/M): A: (1/16)√(900/16) = 0.469; B: (1/32)√(300/32) = 0.0957; C: (1/2)√(600/2) = 8.66. Flask C is greatest. Hence Ans (c).
