Consider the follwing vapour pressure composition graph. `SP` is equal to:
a. `PQ + RS`m , b. `PQ + QR` , c. `SR + SQ` , d. PQ + QR + RS

Text Solution

Verified by Experts

c. According to Dalton's rule: Total pressure of a gaseous solution is equal to the sum of partial pressure.
`:. P_("total") = P_(A) + P_(B)`
=`SR + SQ`
