For a reaction, A + B→ Products, it is observed that doubling the concentration of B causes the reaction
rate to increases four times, but doubling the concentration of A has no effect on the rate of reaction. The rate
equation is therefore
  • a)
    Rate = k[A]0
  • b)
    Rate = k[B]2
  • c)
    Rate = k[A] [B]
  • d)
    Rate = k[A]
Correct answer is option 'B'. Can you explain this answer?

For a reaction, A + B→Products, it is observed that doubling the ...
The reaction you provided, A → B, is a simple representation of a chemical reaction.

In this reaction, A is the reactant and B is the product. The arrow represents the direction of the reaction, showing that A is being converted into B.

Chemical reactions involve the rearrangement of atoms and molecules to form new substances. Reactants are the starting materials that undergo a chemical change to produce products. In this case, A is the reactant undergoing a transformation to form B.

The reaction can be more specifically described by writing the balanced chemical equation, which includes the stoichiometric coefficients for each component. For example, the reaction A + 2B → 3C would indicate that one molecule of A reacts with two molecules of B to produce three molecules of C.

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.
