"Synthesis gas" is a mixture of carbon monoxide and water vapor.
At high temperature synthesis gas will form carbon dioxide and
hydrogen, and in fact this reaction is one of the ways hydrogen is
made industrially. A chemical engineer studying this reaction fills
a flask at with of carbon monoxide gas and of water vapor. He then
raises the temperature considerably, and when the mixture has come
to equilibrium determines that it contains of carbon monoxide gas,
of water vapor...
