- Correlation co-efficient or 'r' value = -0.987
Calculation of Vapour Pressure at 25 °C (298.15 K):
log10 Vp(Pa) = (Slope / Temperature (K)) + Intercept = (-21737.81 / 298.15) + 54.99 =-17.92

- Intercept with y -axis = 47.81
- Slope of the line = -18947.04
- Correlation co-efficient or 'r' value = -0.984
Calculation of Vapour Pressure at 25 °C (298.15 K):
log10 Vp(Pa) = (Slope / Temperature (K)) + Intercept = (-18947.04 / 298.15) + 47.81 =-15.74
