What Is a Second Order Reaction in Chemistry?

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 see that R (the rate of the reaction) would increase or decrease as well. When dealing with half-life, however, we are working with k (the rate constant). WebHere stands for concentration in molarity (mol · L −1), for time, and for the reaction rate constant. The half-life of a first-order reaction is often expressed as t 1/2 = 0.693/k (as ln(2)≈0.693). A typical first-order reaction has a lifetime τ = 1/k.. Fractional order.
