According to the integrated form of the Clausius [KLOU-zee-uhs]-Clapeyron equation solved for the natural logarithm of vapor pressure, vapor pressure and absolute temperature data can be plotted to give a straight line. Which of the following corresponds to the slope?

W) -\(\Delta\)H\({}{\rm vap}\)/R [negative delta H of vaporization over R]

X) \(\Delta\)H\({}{\rm vap}\)/R [delta H of vaporization over R]

Y) -R/\(\Delta\)H\({}{\rm vap}\) [negative R over delta H of vaporization]

Z) R/\(\Delta\)H\({}{\rm vap}\) [R over delta H of vaporization]
W) -\(\Delta\)H\({}{\rm vap}\)/R
