Vapour pressure of carbon monooxide

Description

Vapour pressure (in Pa) of carbon monooxide (CO) was measured for a range of different temperatures (in K).

Usage

data(vapCO)

Format

A data frame with 15 observations on the following 2 variables.

p
a numeric vector
T
a numeric vector

Details

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.
