DATA TAELE Initial Air Pressure (before adding ethonal), P1=102.04kPa Initial Room Temperature. T1=20.2C=2938RK DATAANALYSIS warmed the flask, the air in the flask exerted pressure that you must cakulate. Use the gas law re lationship shown below to complete the calculations. Remember that all gas hw cakculations require Kelvin temperature. Use the P from Trial I as Pr and the Kelvin temperature of Trial 1 as Tl. T1P1=T2P2 2. Calculate and record the Ps. for each trial by subtracting Po from Pawab (Psop=PsotalPair) 3. Prepare and print a graph of Psat (Y-axis) vs. Celsius temperature (X-axis).

The vertical axis for this graph will be the natural logarithm of Prose In Pvoes and the horizontal axis will be the reciprocal of Keivin temperature (1/T). [Youmust submit the aranhon Ariahtspace to set full credits. ) Calculate the linear regression (best-fit line) cquation for this graph. Best linear fit equation: Cakculate Hrap from the slope of the linear regression. (Slope =3Ntar and R=8.314xml1) Hiap=2kJ mol 5. The accepted (theoretical) valuc of the Hwo of cthanol is 42.32kJ mol Compare your experimentally determined value of hap with the accepted value. Calculate the pereent error.
