Hi, I'm researching Langmuir Hinshelwood's kinetic model for sodium borohydride hydrolysis with a cobalt catalyst. I have tried referring to textbooks, ask around, trial and error calculation, but the answers are nowhere close to the example paper. Hope I can get some help to resolve this issue on knowing how to use information from (data obtained through an experiment of hydrogen production rate at different temperatures. Table 1) to get to the graphs Regression vs Ko (equilibrium constant) for optimization Table 4a, Information is given: The H20/Sodium Borohydride molar ratio was equal to 9 (18.9 wt% of sodium borohydride or initial concentration of 6.18 mol/L).

Reaction formula: NaBH + 2H2O > 4H2 + NaBO2

Reference Paper: Langmuir-Hinshelwood kinetic model to capture the cobalt nanoparticles-catalyzed hydrolysis of sodium borohydride over a wide temperature range.
