Reaction Order | MCQs

Explanation

In a zero-order reaction, the rate of reaction is independent of the concentration of the reactants. 

The rate of the reaction is equal to the rate constant 𝑘

Explanation

The order of reaction is defined as the sum of the powers of the concentration terms in the rate law equation.

It shows how the reaction rate depends on the concentrations of reactants.

Explanation

The overall order of a reaction is the sum of the exponents of the concentration terms in the rate expression.

Given the rate expression:

rate=k[A] 2 [B] 3

The exponent for [A] is 2.

The exponent for [B] is 3.

To find the overall order of the reaction, we sum these exponents:

2+3=5

Therefore, the overall order of the reaction is 5.
