A) 166
B) 83
C) 140
D) 280
Correct Answer: C
Solution :
[c] Total V.P., \[P=P_{A}^{0}{{X}_{A}}+P_{B}^{0}{{X}_{B}}=P_{A}^{0}{{X}_{A}}+P_{B}^{0}(1-{{X}_{A}})\] \[=\left( P_{A}^{0}-P_{B}^{0} \right){{X}_{A}}+P_{B}^{0}\] Thus, \[{{P}_{B}}{}^\circ =114\,torr;\,\,P_{A}^{0}-P_{B}^{0}=52\] or \[P_{A}^{0}=166\text{ }torr\] Hence \[P=166\times \frac{1}{2}+114\times \frac{1}{2}=140\text{ }torr\]You need to login to perform this action.
