Assignment:
A flat plate of solid carbon is being burned in the presence of pure oxygen according to the reaction
2C(s) + 3/2 O2(g)→CO(g) + CO2(g)
Molecular diffusion of gaseous reactant and products takes place through a gas film adjacent to the carbon surface; the thickness of this film is 1.0 111111. On the outside of the film, the gas concentration is 40% CO, 20% O,, and 40% CO,. The reaction at the surface may be assumed to be instantaneous; therefore, next to the carbon surface, there is virtually no oxygen.The temperature of the gas film is 600 K, and the pressure is 1 bar. Estimate the rate of combustion of the carbon, in kg/m2-min, and the interface concentration.
Provide complete and step by step solution for the question and show calculations and use formulas.
