Reaction rates a reaction is known to be zero order in [soci2] and second order in [ch3cn] the reaction rate constant is 21 x 10^2 m^-1 s^-1 what fraction of the original amount of soci2 is present after 40 seconds of reaction time elapsed. For example, the reaction may be sufficiently reversible that the back reaction contributes to the observed rate during the assay and/or the products of the reaction may be inhibitors of the enzyme application of the equilibrium model to these non-ideal enzyme reactions can usually be achieved by restricting assays to the initial rate of reaction. - rates of reaction experiment rate of reaction means the rate of formation of a product/disappearance of a reactant, this is useful because we can time the different concentrations reacting with the acid, and give each of them a rate, based on the formula rate = 1/time.
