  Using quantum molecular dynamic simulations, we have studied the
thermophysical properties of warm dense carbon monoxide under extreme
conditions. The principal Hugoniot, which is derived from the equation of
state, shows excellent agreement with available experimental data up to 67 GPa.
The chemical decomposition of carbon monoxide has been predicted at 8 GPa by
means of pair correlation function. Based on Kubo-Greenwood formula, the dc
electrical conductivity and the optical reflectivity are determined, and the
nonmetal-metal transition for shock compressed carbon monoxide is observed
around 43 GPa.
