Reason for the rate of chemical reaction doubling for every 10oC rise in temperature:
Increasing the temperature of a reaction leads to an increase in the rate of the reaction. This phenomenon can be explained by the concept of activated molecules.

Activating Molecules:
- When a reaction takes place, the molecules need to overcome a certain energy barrier known as the activation energy.
- At higher temperatures, the molecules possess more kinetic energy, which increases the likelihood of them reaching the activation energy.
- As the temperature increases, the number of molecules with energy equal to or greater than the activation energy also increases. These molecules are referred to as activated molecules.

Doubling Effect:
- With every 10oC rise in temperature, the number of activated molecules doubles due to the exponential nature of the Arrhenius equation.
- This doubling effect occurs because the rate of reaction is proportional to the number of activated molecules.
- As a result, the rate of the chemical reaction doubles for every 10oC rise in temperature.

Conclusion:
- Therefore, the correct answer is an increase in the number of activated molecules (option D) as the reason behind the rate of chemical reaction doubling for every 10oC rise in temperature.

Similar JEE Doubts

For certain substances such as ammonium chloride, nitrogen peroxide, phosphorus pentachloride, etc. the measured densities are found to be less than those calculatedfrom their molecular formula. The observed densities decrease towards a limit as thetemperature is raised. This is due to the splitting of the molecules into simpler ones. The process is reversible and is called thermal dissociation.Examples :With increase in the number of molecules, the volume increases (pressure remaining constant) and, in consequence, the density decreases. As the temperature rises, more and more dissociation takes place, and when practically complete dissociation occursthe density reaches its lowest limit.The extent of issociation, ice., the fraction of the total number of molecules which suffers dissociation is called the degree of dissociation. Gas density measurements can be used to determine the degree of dissociation. Let us take by general case where one molecule of a substance A splits up into n molecule of B on heating; i.e.,t = 0 at = teq a x nx Total no. of moles Observed molecular weight or molar mass of the mixtureQ.A sample of mixture of A(g), B(g) and C(g) under equilibrium has a mean molecular weight (observe d) is 80.The equilibrium is Find the degree of dissociation for A(g).
