WebJan 2, 2024 · The rate constant is: k = Rate / [A] If you double the concentration of A and the reaction rate increases four times, the rate of the reaction is proportional to the square of the concentration of A. The reaction is second order with respect to A. k = Rate / [A] 2.

WebJan 14, 2015 · Rate of disappearance is given as − Δ [ A] Δ t where A is a reactant. However, using this formula, the rate of disappearance cannot be negative. Δ [ A] will be negative, as [ A] will be lower at a later time, since it is being used up in the reaction. Then, [ A] final − [ A] initial will be negative. WebSep 19, 2024 · A given reaction has a particular rate constant value under a given set of conditions, such as temperature, pressure, and solvent; varying the temperature or the solvent usually changes the value of the rate constant. The numerical value of k, however, does not change as the reaction progresses under a given set of conditions.
