Answer: The rate law expression for the overall reaction is [tex]\text{Rate}=k[A]^2[B][/tex]
Explanation:
Rate law is the expression that expresses the rate of the reaction in terms of the molar concentration of all the reactants each term raised to the power their stoichiometric coefficient in a balanced chemical equation.
In a mechanism of the reaction, the slow step in the mechanism determines the rate of the reaction.
For the given chemical reaction:
[tex]2A+B\rightarrow D[/tex]
The intermediate reaction of the mechanism follows:
Step 1: [tex]A+B\rightleftharpoons C;\text{ (slow)}[/tex]
Step 2: [tex]A+C\rightarrow D;\text{ (fast)}[/tex]
As, step 1 is the slow step. It is the rate determining step
Rate law for the reaction follows:
[tex]\text{Rate}=k[A]^2[B][/tex]
Hence, the rate law expression for the overall reaction is written above.
The rate law is defined as the rate of reaction in which reactants are expressed in their molar concentration raised to the power of their stoichiometric coefficient.
In the given reaction, the slow step determines the rate of reaction.
The chemical reaction is:
2A + B [tex]\rightarrow[/tex] D
The intermediate reaction of the mechanism follows:
Step 1: A + B [tex]\rightleftharpoons[/tex] C (slow)
Step 2: A + C [tex]\rightleftharpoons[/tex] D (fast)
In the given reaction, the first step is a slow step, which determines the rate of the reaction. The rate for the equation can be given as:
Rate = k [A]² [B]
Therefore, the rate law expression for the overall reaction is Rate = k [A]² [B].
