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. WebJul 21, 2024 · Zero-order kinetics is always an artifact of the conditions under which the reaction is carried out. For this reason, reactions that follow zero-order kinetics are often referred to as pseudo-zero-order reactions.
