WebJan 2, 2024 · For a general chemical reaction: aA + bB → cC + dD the rate of the chemical reaction may be calculated as: Rate = k [A] a [B] b Rearranging the terms, the rate constant is: rate constant (k) = Rate / ( [A]a[B]a) Here, k is the rate constant and [A] and [B] are the molar concentrations of the reactants A and B. WebThe solution is actually very simple: the reaction rate is defined as the rate of change of the concentration of a reactant or product divided by its stochiometric coefficient. For the above reaction, the rate (usually given the symbol ν) is therefore ν = - d[N 2] dt= - …
WebThe overall order of reaction is 2 - found by adding up the individual orders. Note: Where the order is 1 with respect to one of the reactants, the "1" isn't written into the equation. [A] means [A] 1. Example 2: This reaction is zero order with respect to A because the concentration of A doesn't affect the rate of the reaction.
