Explanation / Answer
The lab experiment for Clausius-Clapeyron equation is usually performed to determine the heat of vaporization of a volatile liquid.
The pressure inside a sealed container is measured at different temperatures and a plot of natural logarithm of the vapor pressure of the volatile liquid (ln P) vs inverse of the absolute temperature (1/T) is made. The plot is linear and follows the equation
y = mx + c where m = slope of the plot.
The slope of the plot is equal to –H/R where H is the heat of vaporization of the liquid and R is the gas constant. The value of R is known and hence we can easily calculate H.
Ans: (B) Heat of vaporization
