✦ Synopsis

The thermal radiation emitted by the surke of a,mpld flow reactor-is used as a reference standard in a new comparative method for determinin g ckmical activation energies. The surfan temperature, I& thermal radiation, and the products formed in a reactive gas flowing kougb the reactor are all modulated by Lhe periodic on-off switching of a CO, laser that heats the reactor surface to incandescence. The acuvation energy may rhen be obtaked from the energy 01 the thermal photons selected Tor observation and a comparison of tlie-tempcrarure dependencp of the rate of product formation with that of the spectral radnnce of the reactor surface at the chosen wavelength
