Here is the question:

For triethyleamine, the vapor pressure p varies with the temperature according to the following formula:

This formula works only if you use the right units. The pressure must be given in Pascal [Pa]. 1 Pascal is 1 Newton divided by 1 square meter (Pressure is force per area).

The temperature must be given NOT in degrees Celsius but in Kelvin. It is very simple to get from degrees Celsium to Kelvin: just add or subtract 273. For instance, 273 K = 0 deg C. 373 K = 100 deg C, and so on...

Now the 1.000.000 Kroner question: Find out the values for the constants a and b in the formula, if you know two things: At temperature T₁ = 100.0 K, we have a vapor pressure of p₁ = 0.44 Pa. And at temperature T₂ = 140.0 K, we have a vapor pressure of p₂ = 93.33 Pa.
