If the rate of reaction does not depends upon the initial concentration of reactant, the order of reaction is : Correct Answer zero

Concept:

Rate of the reaction

  • The speed of a chemical reaction is called the rate of the reaction.
  • As the reaction proceeds, the amount of reactants decreases whereas the amount of products increases. 

Consider a chemical reaction, 

aA + bB → products. 

The rate of the reaction is directly proportional to the concentration of the reactants.

Rate = Ka b

K-rate constant.

-Concentration of reactant A.

- Concentration of reactant B.

The most important orders of reaction 

  • Zero-order reaction.

Rate of the reaction is independent of the concentration of the reactants.

Rate =K

  • First-order reaction.

Rate of the reaction depends on the concentration of one of the reactants involved in the reaction. 

Rate=K

  • Second-order reaction.

Rate of the reaction depends upon the concentration of two reactant molecules. 

Rate= K2

Explanation:

The reaction in which rate doesn't depend on the concentration of reacting species is known as Zero order reaction. 

0

Rate = K

So, If the rate of reaction does not depend upon the initial concentration of reactant, the order of the reaction is Zero.

Rate constant for a first order reaction does not depend upon reaction time, extent of reaction and the initial concentration of reactants ; but it is a function of reaction temperature. In a chemical reaction, the time required to reduce the concentration of reactant from 100 gm moles/litre to 50 gm moles/litre is same as that required to reduce it from 2 gm moles/litre to 1 gm mole/litre in the same volume. Then the order of this reaction is
For the reaction, A = X + Y, the respective concentrations are CA, CX and CY. The forward reaction rate constant is kf and the backward reaction rate constant is kb. Choose the correct statement from the following:

R. The backward reaction rate will essentially be first order, if the forward reaction rate is first order.
S. Activation energy for the first order forward reaction will be independent of temperature.
In a reaction, A + B → Product, when the concentration of B is doubled the rate is doubled, and when the concentrations of both the reactant doubled the rate is increased by a factor of 8, rate law can be written as: 2 b) Rate = k2 c) Rate = k d) Rate = k22
