For the reaction A + B →  products, it is observed that: [2009]
(1) On doubling the initial concentration of A only, the rate of reaction is also doubled and
(2) On doubling the initial concentrations of both A and B, there is a change by a factor of 8 in the rate of the reaction.
The rate of this reaction is given by: 
  • a)
    rate = k [A] [B]2
  • b)
    rate = k [A]2 [B]2
  • c)
    rate = k [A] [B]
  • d)
    rate = k [A]2 [B]
Correct answer is option 'A'. Can you explain this answer?

For the reaction A + B→ products, it is observed that: [2009](1) ...
When concentration A is doubled, rate is doubled. Hence order with respect to A is one.
When concentrations of both A and B are doubled, rate increases by 8 times hence order with respect to B is 2.
∴   rate = k [A]1 [B]2
Total order = 1 + 2 = 3

For the reaction A + B→ products, it is observed that: [2009](1) ...
The reaction A → B is a chemical reaction where substance A is converted into substance B. This reaction can occur spontaneously or may require the input of energy, such as heat or light.

The reaction can be represented by a chemical equation:

A → B

In this equation, A represents the reactant and B represents the product. The arrow indicates the direction of the reaction, with A being converted into B.

The reaction can be classified as a decomposition reaction, as substance A is being broken down into substance B.

The rate of the reaction can be influenced by factors such as temperature, concentration of reactants, and the presence of catalysts. The reaction rate is the speed at which substance A is converted into substance B.

Overall, the reaction A → B involves the conversion of substance A into substance B and can be influenced by various factors.

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.
