Rate constants determined from Arrhenius equation are fairly accurate for simple and complex molecules because only those molecules which have proper orientation during a collision (i.e., effective collision) and sufficient kinetic energy lead the chemical change.

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.
The correct answer is option 'C', i.e., Assertion is true but the reason is false.
Explanation:
The Arrhenius equation is a mathematical relationship between the rate constant of a reaction and the temperature at which the reaction is taking place. It is given by the equation:
k = Ae^(-Ea/RT)
Where:
- k is the rate constant
- A is the pre-exponential factor or frequency factor
- Ea is the activation energy
- R is the gas constant
- T is the temperature
Assertion is true:
The rate constants determined from the Arrhenius equation are fairly accurate for simple as well as complex molecules. This is because the Arrhenius equation takes into account the effect of temperature on the rate of reaction. As the temperature increases, the rate constant also increases, indicating a faster reaction. This relationship holds true for both simple and complex molecules.
Reason is false:
The reason given in the statement is that reactant molecules undergo chemical change irrespective of their orientation during collision. However, this is not entirely accurate. The orientation of reactant molecules during collision does play a role in determining the reaction rate. In many chemical reactions, the reactant molecules need to collide in a specific orientation in order for the reaction to occur. This is known as the "collision theory" of chemical reactions. The collision theory states that reactant molecules must collide with sufficient energy and in the correct orientation in order to form products. Therefore, the reason given in the statement is incorrect.
In conclusion, while the assertion is true that rate constants determined from the Arrhenius equation are fairly accurate for simple as well as complex molecules, the reason given to support this assertion is false. The orientation of reactant molecules during collision does affect the rate of reaction.
