Which one is not correct ?a)Rate of zero order reaction depends upon i...
Explanation:

Zero Order Reaction: A zero-order reaction is a chemical reaction in which the rate of the reaction is independent of the concentration of the reactant. The rate of a zero-order reaction is constant, and it is measured in units of concentration/time.

Rate of Zero Order Reaction: The rate of a zero-order reaction does not depend upon the initial concentration of the reactant. Instead, it depends solely on the rate constant, which is a constant for a given reaction at a given temperature. The rate constant, k, determines how fast the reaction will proceed, regardless of the initial concentration of the reactant.

t1/2 of Zero Order Reaction: The half-life, t1/2, of a zero-order reaction depends upon the initial concentration of the reactant. The half-life is the time required for the concentration of the reactant to decrease to half of its initial value. In a zero-order reaction, the half-life is given by the equation t1/2 = [A]0/2k, where [A]0 is the initial concentration of the reactant and k is the rate constant.

First Order Reaction: A first-order reaction is a chemical reaction in which the rate of the reaction is proportional to the concentration of the reactant. The rate constant, k, for a first-order reaction is independent of the initial concentration of the reactant.

t1/2 of First Order Reaction: The half-life, t1/2, of a first-order reaction is independent of the initial concentration of the reactant. In a first-order reaction, the half-life is given by the equation t1/2 = ln2/k, where k is the rate constant.

Conclusion:

In conclusion, option 'A' is not correct. The rate of a zero-order reaction does not depend upon the initial concentration of the reactant. Instead, it depends solely on the rate constant, which is a constant for a given reaction at a given temperature. The rate constant, k, determines how fast the reaction will proceed, regardless of the initial concentration of the reactant.

Zero order of a reaction doesn't depend on the initial concentration of a reactants.
A -> B
R = k[A]^0 = K
R = k[2A]^0 = K
R = k[3A]^0 = K
so, it does not depend on [A]

Similar Class 12 Doubts

Read the passage given below and answer the following questions:The rate of a reaction, which may also be called its velocity or speed, can be defined with relation to the concentration of any of the reacting substances, or to that of any product of the reaction. If the species chosen is a reactant which has a concentration c at time t the rate is - dc/dt, while the rate with reference to a product having a concentration x at time t is dx/dt. Any concentration units may be used for expressing the rate; thus, if moles per liter are employed for concentration and seconds for the time, the units for the rate are moles litre–1sec–1. For gas reactions pressure units are sometimes used in place of concentrations, so that legitimate units for the rate would be (mm. Hg) sec–1 and atm. sec–1 The order of a reaction concerns the dependence of the rate upon the concentrations of reacting substances; thus, if the rate is found experimentally to be proportional to the ath power of the concentration of one of the reactants A, to the both power of the concentration of a second reactant B, and so forth, via., rate = k CAα CAβ the over-all order of the reaction is simply n = α + β + ----- (2) Such a reaction is said to be of the αth order with respect to the substance A, the βth order with respect to B.In the following questions, a statement of Assertion followed by a statement of Reason is given. Choose the correct answer out of the following choices on the basis of the above passage.Assertion: For a reaction: P + 2Q → Products, Rate = k [P]1/2[Q]1 so the order of reaction is 1.5Reason: Order of reaction is the sum of stoichiometric coefficients of the reactants.
