WebCalculate the mass ratio of CH 4 to O 2 required for complete combustion. Solution: This is just the ratio of the molar mass of CH 4 (16 g) to that of two moles of dioxygen (2 x 32 g) Thus (64 g) / (16 g) = 4/1 = 4.0. Complete combustion of each kg of methane consumes 4 kg of dioxygen, which is supplied by the air. WebFeb 2, 2024 · Add the order for all reactants together. The overall order of a reaction is the sum of each reactants' orders. Add the exponents of each reactant to find the overall reaction order. This number is usually less than or equal to two. [3] For example, if reactant one is first order (an exponent of 1) and reactant two is first order (an exponent ...
