Gas

A

(mol. mass 16) and gas

B

(mol. mass 4) are confined into a vessel at partial pressure of 2 atm each at

27^\circ\text{C}

. The gases are then allowed to effuse out at

27^\circ\text{C}

through a value till the pressure inside the vessel becomes 2 atm after which the valve is closed and the gases are heated to

127^\circ\text{C}

and allowed to react as

A + B \rightleftharpoons C

K_P = 0.1 \text{ atm}^{-1}

. Calculate the partial pressure of

C

at equilibrium assuming

C

is not formed till the effusing process is completed at

27^\circ\text{C}
