vapCO {nlrwr} | R Documentation |
Vapour pressure (in Pa) of carbon monooxide (CO) was measured for a range of different temperatures (in K).
data(vapCO)
A data frame with 15 observations on the following 2 variables.
p
T
Two common models that could be fit to the data are the Clapeyron and Antoine equations.
The theoretical Clapeyron equation is:
log(p) = A - B/T
The semi-empirical Antoine equation is:
log(p) = A - B/(T+C)
The coefficients A,B,C are tabulated for many compounds.
The Antoine equation provides the better fit.
