Question Benzene and toluene form two ideal solution \( \mathrm{A} \) and \( \mathrm{B} \) at \( 313 \mathrm{~K} \). Solution A (total pressure \( \mathrm{P}_{\mathrm{A}} \) ) contains equal mole of toluene and benzene. Solution B contains equal masses of both (total pressure \( \mathrm{P}_{B} \) ). The vapour pressure of pure benzene and pure toluene are 160 and \( 60 \mathrm{~mm} \mathrm{Hg} \) respectively at \( 313 \mathrm{~K} \). Calculate the value of \( \mathrm{P}_{\mathrm{A}} / \mathrm{P}_{\mathrm{B}} \).
(A) 0.694
(B) 0.496
(C) 0.964
(D) 0.732πŸ“²PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
