A container fitted with frictionless massless piston consists of five valves-I, II, III, IV and V . These valves open automatically if pressure exceed over 1.5, 2.2, 2.5, 4.4 and 4.8 atm respectively.

Question

A container fitted with frictionless massless piston consists of five valves-I, II, III, IV and $V$ . These valves open automatically if pressure exceed over 1.5, 2.2, 2.5, 4.4 and 4.8 atm respectively. Under the given initial conditions (mentioned in given diagram) system is in state of equilibrium. Piston is now pressed in downward direction very slowly.

[Note: Consider the diameter of valve tube negligible and temperature remains constant.]

At valve I position of piston, 1 × 60 = P × 45 ⇒ P = 1.33 < 1.5 So, valve I does not open. After opening of valve III, number of moles remaining = 0.0821 × 300 2.5 × 20 × 821 × 1 0 − 3 ​ = 3 5 ​ .
