Q. Which one of the following represents the graph between $\log p(on\ Y - axis)and\ \frac{1}{T}\ (on\ X - axis)?$ $(p = vapour\ pressure\ of\ a\ liquid,\ T = absolute\ temperature)$
A) [image:5_image24.emf]
B) [image:5_image25.emf]
C) [image:5_image26.emf]
D) [image:5_image27.emf]
Explanation
(c)
According to Clausis-Clapeyron, if a graph is plotted between $\log p\ and\frac{1}{T},$ a straight line is obtained with negative slope.
