Use the Clausius-Clapeyron equation to determine the slope (AH/R) for the chemical methyl ethyl ketone over the temperature range 50 °C to 80 °C. Once you have calculated this slope value, then also determine the value of the heat of vaporization (AH,) of methyl ethyl ketone in units of kJoules/mole, and compare your calculated value. Be sure you use an appropriate value of the R gas constant.
