Mixture of volatile components A and B has a total vapour pressure (in torr)p=`254-119 x_(A)`is where`x_(A)`mole fraction of A in mixture .Hence`P_(A)^@`and `P_(B)^@`are(in torr)

A

254119

B

119254

C

135254

D

154, 119

Text Solution

Verified by Experts

The correct Answer is:
D
`p_("Total") = p_A^@X_A + p_B^@X_B`
`=p_A^@X_A + p_B^@X_B`
`=p_B^@ - (p_B^@ - p_A^@) X_A`
