Case: Read the passage and answer the following questions
In the rate equation Rate = k [A]x[B]y
x and y indicate how sensitive the rate is to the change in concentration of A and B. Sum of these exponents, i.e., x + y gives the overall order of a reaction whereas x and y represent the order with respect to the reactants A and B respectively. Hence, the sum of powers of the concentration of the reactants in the rate law expression is called the order of that chemical reaction. Order of a reaction can be 0, 1, 2, 3 and even a fraction.
Which of the following is true for the value of rate constant of a pseudo first order reaction?
Answer & explanation
Correct answer: option 4
The value of the rate constant of pseudo-first-order reaction depends on the concentration of reactants present in excess amount. A pseudo-first-order reaction can be defined as a second-order or bimolecular reaction that is made to behave like a first-order reaction.
