isom {IPEC}

Data on Biochemical Oxygen Demand

Description

Data on the reaction rate of the catalytic isomerization of n-pentane to isopentane versus the partial pressures of hydrogen, n-pentane, and isopentane.

Usage

data(isom)

Details

There are four columns in the data set:

'y' is the vector of experimental reaction rate (in 1/hr);

'x1' is the vector of partial pressure of hydrogen;

'x2' is the vector of partial pressure of n-pentane;

'x3' is the vector of partial pressure of isopentane.

Note

There were errors about the definitions of 'x2' and 'x3' in page 272 in Bates and Watts (1988). Here, we redefined them according to the paper of Carr (1960).
