Equations are obtained for the ultrasound intensity and for the number of phonons per scattered light quantum in stimulated scattering in thermodynamically nonequilibrium media when the rates of chemical reactions depend on the optical intensity. Estimates show that in gas mixtures such as CO/sub 2/ and n-C/sub 3/F/sub 7/I at a total pressure of 0.5 atm, in which exothermic reactions between iodine atoms and organofluoric radicals occur as a result of photolysis of n-C/sub 3/F/sub 7/I, light having an intensity of approx.10/sup 5/ W/cm/sup 2/, resonantly interacting with iodine atoms, can excite ultrasound having an intensity of tenths of a watt per square centimeter at a frequency of approx.1 MHz. In this case, approx.10/sup 4/ phonons are produced per scattered photon.
