An ideal gas is enclosed in a vessel at initial pressure P 0 and volume V 0 , Temp T 0 . It is found that due to leakage gas is escaping from the vessel at a rate such that 
= – αP, α is positive constant where 
is the rate of change of moles, then choose the correct alternative -
A
Pressure in the vessel after a long time becomes zero
B
Pressure in the vessel decreases to half of its initial value after a time 
λ n(2)
λ n(2)
C
At t = 
; Pressure in the vessel is 
; Pressure in the vessel is
D
At t = 
; Pressure in the vessel is 
; Pressure in the vessel is
