Determine initial rate of reaction

WebUnder these conditions, the average rate of the reaction determined for this period will be a close approximation of the reaction rate corresponding to the initial concentration of reactants which is the initial rate of the reaction: Initial rate = k'[I –] 0 n[H 2O2]0 m where [I] 0 = initial concentration of iodide WebThe reaction rate can depend on how concentrated our reactants are. A chemical reaction’s rate law is an equation that describes the relationship between the concentrations of reactants in the reaction and the reaction rate. In the standard form, the rate law equation is written as: R = k [A] n [B] m.
