Question: please help on point 1 x, point 2 y, run The vapor pressure, P. of a certain liquid was measured at two temperatures, T. The
The vapor pressure, P. of a certain liquid was measured at two temperatures, T. The data is shown in the table. T(K) P (kPa) 225 3.79 775 6.16 Keep the pressure units in kilopascals. If you were going to graphically determine the enthalpy of vaporizaton, AH cup. for this liquid, what points would you plot? To avoid rounding errors, use three significant figures in the x-values and four significant figures in the y-values. 0.0044 point 1: x= point 1: y = 1.332 Incorrect point 2: x = 0.00129 2.865 point 2: y = lacorrect Determine the rise, run, and slope of the line formed by these points. rise 0.533 -0.0081 run Incorrect slope = -171.382 What is the enthalpy of vaporization of this liquid? = 1424.87 J/ mol
