WebMechanism 2. Remember that in simple cases, where the slow step is the first step of the mechanism, the orders tell you what is taking part in the slow step. In this case, the … WebThe reaction rate can depend on how concentrated our reactants are. A chemical reaction’s rate law is an equation that describes the relationship between the concentrations of reactants in the reaction and the reaction rate. In the standard form, the rate law equation is written as: R = k [A] n [B] m.

How to Determine the Reaction Order - Chemistry Steps

WebThe units of the rate constant, k, depend on the overall reaction order.The units of k for a zero-order reaction are M/s, the units of k for a first-order reaction are 1/s, and the units of k for a second-order reaction are 1/(M·s). Created by Yuki Jung. WebA reaction mechanism is the sequence of elementary steps by which a chemical reaction occurs. Many reaction mechanisms contain one step that is much slower than the others; this step is known as the rate-determining step.
