The dependence of the rate of a chemical reaction upon the concentration of reactants is obtained experimentally. For any time instant, the reaction velocity can be calculated from the tangent to the curve of the variation of concentration of reactants or products as a function of time. Since...
[17]. Also indicated are the rate constants determined by Faßheber et al. [102] and Lamoureux et al. [52]. Table 5. Temperature dependence of the rate constant for the reaction NCN + H → CH + N2 (R-1a), expressed in the form k-1a = A (T / K)n exp(–E / RT). A...
