Question

Data and Calculations Volume (mL) Pressure iatrnkul constant, k ( Pn) Constant, k(PxV 1.4 2. Processing the Data 1. With the best-fit curve still displayed, choose Interpolate from the Analyze menu. A verti- cal cursor now appears on the graph. The cursor's volume and pressure coordinales are displayed in the floating box. Move the cursor along the regression line until the volume ue is 5.0 ml. Note the corresponding pressure valuc. Now move the cursor until thc volume value is doubled (10.0 mL. Bsed on your data, what happens to the prewar when the volume is dowbled? Show the pressure values in your answer LI 806 1664011 2. What experimental factors are assumed to be constant in this experimen 69

Explanation / Answer

Data and calculations,

The given table has values of Pressure and volume

So constant k is calculated by P x V

From top to bottom

k = (P x V) = 5.8 x 1.86 = 10.788

k = (P x V) = 7.8 x 1.41 = 10.998

k = (P x V) = 9.8 x 1.13 = 11.074

k = (P x V) = 11.8 x 0.92 = 10.856

k = (P x V) = 13.8 x 0.79 = 10.902

k = (P x V) = 16.8 x 0.68 = 11.424

k = (P x V) = 19.8 x 0.54 = 10.692

1. Pressure and volume are inversely proportional to each other, therefore, when volume is doubled the pressure would reduce to half the initial value.

2. In the given experiment of Pressure versus volume study, it is asumed that the temperature of the system remains a constant. Also the moles of compound would remains unchanged througout the experimental period.
