Analytic solutions have been obtained for the equilibrium sublimation of a carbon surface in atmospheres whose elemental composition consists of carbon, hydrogen, oxygen, nitrogen, and an inert element. The solutions are expressed in simple algebraic expressions for the surface mass transfer parameter B prime and are computationally trivial, requiring only the evaluation of a quadratic equation. The analytic expressions are essentially exact and include an arbitrary number of carbon sublimation species and all the dominant gas phase reactions, while ignoring only those species which exist in trace amounts. The solutions are in excellent agreement with exact results from the ACE chemistry code.
