Clausisus Claperyron Problem. Find the delta H, graph and calculate the slope. Data: Temeratrue in Celcisus- 0, 20, 25, 40, 70, 100. Pressure in Torr- 4.579, 17.535, 23.756, 53.324, 233.7, 760. Plot all 6 data points.

Expert Solution

Solution :-

To calculate the Delta H vap we need to plot a graph of the temperature and pressure

ln P vs 1/T

need to use temperaure in kelvin

Following image shows the plot

the slope of the line is the equals to the - Delta H/R

so the - delta H = slope * R

-delta H = -5199.6 * 8.314 J per mol

- delta H = -43230 J /mol

multiplying by negative sign on both side we get

delta H = 43230 J /mol

lets convert it to kJ

43230 J/mol * 1 kJ / 1000 J = 43.23 kJ/mol
