Q 2653834744.     An ideal mixture of liquids A and B with 2 moles of A and 2 moles of 8 has a total yapour pmssue of 1 atm at a certain temperature. Another mixture with 1 mole of A and 3 moles of B has ai vapour pressure greater than 1 atm. But if 4 moles of C are added to the second mixture, the vapour pressure comes down to 1 atm. Vapour pressure of C, P_c^o= 0.8 atm. Calculate the vapour pressures of pure A and pure B.
A

P_A^0 = 1.4 atm, P_B^o = 0.7 atm

B

P_A^0 = 1.2 atm, P_B^o = 0.6 atm

C

P_A^0 = 1.4 atm, P_B^o = 0.6 atm

D

P_A^0 = 0.6 atm, P_B^o = 1.4 atm
