It has been demonstrated that the reaction between gaseous chlorine nitrate and water on room temperature liquid sulfuric acid (95.6%) surfaces yields hypochlorous acid in the gas phase. First‐order loss rate constants for chlorine nitrate (equivalent to a value of the sticking coefficient γ = 3.2 × 10 −4 ) have been determined. This value is five orders‐of‐magnitude greater than reported values on similar areas of more inert surfaces. Application of results of this type to stratospheric models must await ongoing studies at lower temperatures.
