Respuesta :
The order with respect to A is 2
The order with respect to B is 0.
The overall reaction order is 2.
Explanation:
The rate of chemical equation is represented by its rate equation. Here the rate equation of the given chemical reaction is
[tex]rate=k[B]^2[/tex]
Here k represents the rate constant .
Order of the reaction with respect to its individual reactants is represented by the power of the the reactants in the rate equation.
Here the power of the reactant A is 0 and the power of reactant B is 2.
Hence the order with respect to A is 0 and order with respect to B is 2.
The overall order of the reaction is given by the sum of the powers of the reactants in the rate equation.
Hence the total order=2+0=2
The order of the reaction with respect to A is 0.
The order of the reaction with respect to B is 2.
Overall reaction order for the given reaction 2.
From the question,
The rate law for the given reaction is
Rate = k[B]²
This means the rate of the reaction is solely dependent on the concentration of B.
The rate law for the reaction can also be written as
Rate = k[B]²[A]⁰
From the rate law above, we can deduce that
The order of the reaction with respect to A is 0. That is, zero order
Also,
The order of the reaction with respect to B is 2. That is, second order.
Now, for the overall reaction order
Overall reaction order is the sum of the powers to which all reactant concentrations appearing in the rate law are raised.
∴ Overall reaction order for the given reaction = 2 + 0 = 2. That is, the reaction is second order reaction overall
Hence,
The order of the reaction with respect to A is 0.
The order of the reaction with respect to B is 2.
Overall reaction order for the given reaction 2.
