Question
Transcribed Image Text:The vapor pressure curve for phosphorus oxychloride (POC13) is described
by the following equation
Pvap = 0.0003 T³ +0.0136 T² +0.3702 T+7.2708
Pvap. (mmHg), T (Kelvin)
1. Find Pvap, in the temperature range -30 °C to 60 °C using 10 °C increments.
2. Using the Charting guidelines, draw the curve of Pvap. vs. T (K).
Hints:
1- Construct a table like the following on Excel:
T(°C) T (Kelvin) Pvap.(mmHg)
-30
243
-20
-10
2- Exponent (power) function in Excel formula is (^).
3- Proper labeling of chart title, axes
The solubility of Oxygen gas (O2(g)) in water in units of (g 0₂/100 g H₂O) is
described by the following equation:
Solubility=-1×10 T³ +2×10 T²-2×10 T +0.0069
(a) Using the Charting guidelines, Plot the solubility of O2(g) in water as a function of
temperature over the range 0-100 °C using 5 °C increments.
(b) What is the effect of increasing temperature on the solubility of O2(g).
Note: "A" as a function of "B" OR "A" vs. "B"
→ "A" is the y-variable and "B" is the x-variable
