Catalytic converters are the most common option for controlling emissions of polluting gases by internal combustion engines in automobiles, accelerating the conversion of nitrogen oxides into nitrogen and oxygen gases. A chemical reaction that can be used for the conversion of nitric oxide into non-polluting gases is the reaction of this gas with hydrogen, resulting in nitrogen and water gases, as shown in the chemical equation below: 2 NO(g) + 2 H2(g) → N2(g) + H2O(g) The kinetics of this reaction at a temperature of 1250 °C is represented in the following table, which indicates the influence of the concentration of the reactants on the reaction rate, obtained through three experiments conducted under the same conditions EXPERIMENTO [NO] (MOL/L) [H2] (MOL/L) V0 (MOL/Ls) 1 0,20 0,08 0,05 2 0,40 0,08 0,20 3 0,40 0,16 0,40 Determine the rate law for this chemical reaction, the rate constant, and its respective unit. Calculate the rate when the concentration of NO is 0.30 mol/L and the concentration of H2 is 0.10 mol/L. Also, mention a factor that may influence the rate of the reaction.
