Kinetics of the Heterogeneous Reaction CO + O = CO(sub 2) on Inorganic Oxide and Water Ice Surfaces: Implications for the Martian Atmosphere
The heterogeneous reaction CO + O - CO(sub 2) on water ice and varios inorganic oxide surfaces has been investigated in order to evaluate the proposition that this heterogeneous reaction may contribute to the CO(sub 2) stability in the Martian atmosphere.

Surface Areas and Morphology of Thin Ice Films
Thin ice films formed by deposition from the vapor phase in a fast flow-tube reactor have been used to simulate polar stratospheric cloud surfaces in order to obtain laboratory data on uptake and heterogeneous reaction rates. Surface areas are determined from BET (Brunauer, Emmett, and Teller) analysis of gas adsorption isotherms. The results for ices prepared at 196 K or 77 K are consistent with previous data on thicker ice films. Environmental scanning electron microscopy is used to obtain particle sizes and shapes, and to investigate the morphology of the ices on borosilicate or silicon windows. In addition, the uptake of HCI on ice films prepared at 196 K is investigated. The results suggest that the layer model we have previously developed for analysis of uptake and heterogeneous reaction rates on ice films is valid. Detailed information will be presented at the conference.

Heterogeneous Chemistry Important in the Polar Stratosphere
Aircraft emissions have been thought to enhance the formation of polar stratospheric clouds in the Arctic winter, and therefore heterogeneous reactions on the surfaces of these clouds may accelerate the polar ozone depletion.
