Results and discussion

Vapour pressure
Temp.:
30 °C
Vapour pressure:
4.4 kPa

Any other information on results incl. tables

For tables of results see attached background material for:

- Vapour pressure at different temperatures

- Calculation for log P versus 1/T curve

Estimation of vapour pressure at 25 C form the log P versus 1/T curve

Equation of lop P versus 1/T curve:

log P = 10.942 -(2220.3/T)

At 25 °C; T = 273.15 + 25 = 298.15 k

log P = 10.942 -(2220.3/289.15)

log P = 3.4951

P = 3.1 kP
