Regression calculation

- A graph was plotted of Log₁₀(vapour pressure in hPa) (y axis) against 1/(temperature in K) (x axis).

- For a copy of this graph please see attached illustration.

- The calculated regression line was: y = -2139.5x + 7.534

- The coefficient of determination (R²) of this line was 0.9999

Conclusions:
The vapour pressure of nonanal was determined to be 2 hPa at 20 °C in a study to DIN EN 13016-2 by extrapolating from recorded vapour pressures at higher temperatures.
