The exponential term in the expression for the forward reaction rate in a non-equilibrium dissociating gas has been exploited to produce three simplified, approximate, concepts which assist in understanding the effects of non-equilibrium in hypervelocity flows. They are, a constant temperature approximation, the thermodynamic decoupling of the temperature, and pressure gradient reaction quenching. These concepts are seen to allow satisfactory prediction of shock stand-off on a sphere, the growth of shock detachment on a wedge, the variation of shock stand-off on a delta wing, and the density variation along a streamline downstream of a curved shock.
