For a general gasification reactor considering the main generic gasification equations, how would you calculate the rate constant (K) . Compositions of MSW is known.

\begin{tabular}{c|c|c} C+CO2=2CO & Boudouard & 1 \\ \hline C+2H2=CH4 & Methanation & 2 \\ \hline C+H2O=CO+H2 & Water gas & 3 \\ \hline CH4+H2O=CO+3H2 & Steam Methane reforming & 4 \\ \hline CO+H2O=CO2+H2 & Water gas shift & 5 \\ \hline CH4+0.5O2=CO+2H2 & Methane oxidation & 6 \end{tabular}
