Question

For a binary ideal liquid solution,the total pressure of the solution is given as

Answer 1

Answer
ptotal=p∗B+(p∗A−P∗B)xAptotal
=pB∗+(pA∗−PB∗)xA

We have

ptotal=pA+pB =xAP∗A+xBP∗B+(1−xA)P∗B =p∗B+(p∗A−P∗B)x Aptotal =pA+pB =xAPA∗+xBPB∗+(1−xA)PB∗ =pB∗+(pA∗−PB∗)xA

Here is your answer...

Hope this helps you friend....

Answer 2

Answer : ptotal=p∗B+(p∗A−P∗B)xAptotal=pB∗+(pA∗−PB∗)xA

We have

ptotal=pA+pB=xAP∗A+xBP∗B+(1−xA)P∗B=p∗B+(p∗A−P∗B)xA
