Query: Contributions of steady heat conduction to the rate of chemical reaction   We have derived the effect of steady heat flux on the rate of chemical
reaction based on the line-of-centers model using the explicit velocity
distribution function of the steady-state Boltzmann equation for hard-sphere
molecules to second order. It is found that the second-order velocity
distribution function plays an essential role for the calculation of it. We
have also compared our result with those from the steady-state
Bhatnagar-Gross-Krook(BGK) equation and information theory, and found no
qualitative differences among them.
