In a combustion process where 1 kg mole of carbon (𝐶C) reacts with 1 kg mole of oxygen (𝑂2O2​) to produce 1 kg mole of carbon dioxide (𝐶𝑂2CO2​), there is no net accumulation of any of the reactants or products. The balanced chemical equation for the combustion of carbon can be written as: 𝐶+𝑂2→𝐶𝑂2C+O2​→CO2​ From this equation, we see that 1 kg mole of carbon reacts completely with 1 kg mole of oxygen to form 1 kg mole of carbon dioxide. There are no excess reactants or products left over. Therefore, the accumulation in this steady-state combustion process is \textbf{0 kg mole}. So, the correct answer is: 00​
