First order reaction rate constant equation
Webrate of reaction = v = - d [A]/ dt = d [B]/ dt = k 1 [A] where k 1 is the 1st-order rate constant for the forward reaction, [A] is the reactant concentration, and [B] is the product concentration. The rate of the reaction (or its velocity v) is given either by the rate of disappearance of [A] or appearance of [B]. Web8 years ago. In earlier videos we see the rate law for a first-order reaction R=k [A], where [A] is the concentration of the reactant. If we were to increase or decrease this value, we …
