Note: 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.
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.
An Arrhenius equation i.e. k=Ae^(-E_a/RT) .
Where A is the frequency factor and term e^(-E_a/RT) corresponds to the fractions of molecules having kinetic energy equal to or greater than the activation energy.
The rate constant can be determined for a reaction from the above equation if the different values of temperature are given and it is accurate for simple as well as complex reactions.
Reactant molecules with sufficient kinetic energy and with proper orientation of collision undergo a chemical change and lead to the formation of a product that is why frequency factor is added in Arrhenius Equation.
Thus, the assertion is true and the reason is false.
