Consider the following figure at 500 K.Assuming ideal gas behaviour, calculate the total pressure if the barriers are removed from the compartment.Assume that the volume of barriers is negligible.

SOLUTION :Number of moles of A,B,C and D are GIVEN as :
`n_A=(PV)/(RT)=(1xx1)/(RT),n_B=(1.5xx2)/(RT)=(3)/(RT)`
`n_C=(2.5xx4)/(RT)=(10)/(RT),n_D=(2XX3)/(RT)=(6)/(RT)`
`n=n_A+n_B+n_C+n_D=(1+3+10+6)/(RT)=20/(RT)`
Total PRESSURE is given as
`P_("Total")=(nRT)/Vimplies P_("Total")=20/(RT)xx(RT)/7=2.85`
