Question

Assertion: Rate constants determined from Arrhenius equation are fairly accurate for simple as well as complex molecules.

Reason: Reactant molecules undergo chemical change irrespective of their orientation during collision.

Options

  • Both assertion and reason are correct and the reason is correct explanation of assertion.

  • Both assertion and reason are correct but reason does not explain assertion.

  • Assertion is correct but reason is incorrect.

  • Both assertion and reason are incorrect.

  • Assertion is incorrect but reason is correct.

MCQ

Solution

Assertion is correct but reason is incorrect.

Explanation:

To Arrhenius equation `(k =Ae^((-Ea)/(RT)))`; it is found almost accurate for single as well as complex reaction.

However, orientation is essential for the reactant molecules participating in the reaction.

Read the following passage and answer the questions that follow:

The rate of reaction is concerned with decrease in the concentration of reactants or increase in the concentration of products per unit of time. It can be expressed as instantaneous rate at a particular instant of time and average rate over a large interval of time. A number of factors such as temperature, concentration of reactants, catalyst affect the rate of reaction. Mathematical representation of rate of a reaction is given by rate law:

Rate = k[A]x [B]y

x and y indicate how sensitive the rate is to change in concentration of A and B. Sum of x + y gives the overall order of a reaction.
When a sequence of elementary reactions gives us the products, the reaction is called complex reaction. Molecularity and order of an elementary reaction are same. Zero-order reactions are relatively uncommon but they occur under special conditions. All natural and artificial radioactive decay of unstable nuclei takes place by first-order kinetics.
