FAQs on Chemical Kinetics Mock Test for JEE Main 2025-26: Ultimate Preparation Guide
1. What is chemical kinetics?
Chemical kinetics is the branch of chemistry that studies the rate of chemical reactions and the factors that affect these rates. It provides insights into how quickly reactants are converted to products, how concentration, temperature, and catalysts influence the reaction, and helps determine the mechanisms of reactions.
2. What is the difference between average rate and instantaneous rate of reaction?
The average rate of reaction is calculated over a specific time interval and represents the change in concentration of reactants or products over that period. The instantaneous rate refers to the rate at a particular moment and is found by drawing a tangent to the concentration vs. time curve at a specific point.
3. How does temperature affect the rate of a chemical reaction?
Temperature increases the rate of a chemical reaction by providing reactant particles with more kinetic energy. Higher temperatures lead to more frequent and energetic collisions, thus increasing the probability of effective collisions and formation of products.
4. What is the rate law for a reaction?
The rate law expresses the relationship between the rate of a reaction and the concentration of its reactants. For a general reaction aA + bB → products, the rate law is: Rate = k [A]m [B]n, where k is the rate constant and m, n are the order of the reaction with respect to A and B, respectively.
5. What is the order of a reaction and how is it determined?
The order of a reaction is the sum of the powers to which the concentrations are raised in the rate law equation. It is determined experimentally by observing how changes in reactant concentrations affect the reaction rate.
6. How does a catalyst affect the rate of a reaction?
Catalysts increase the reaction rate by providing an alternative reaction pathway with a lower activation energy. They do not affect the equilibrium position but help the system reach equilibrium faster.
7. What is activation energy?
Activation energy (Ea) is the minimum amount of energy required for reactant molecules to undergo a successful collision leading to reaction. It is represented in the Arrhenius equation and can be lowered by catalysts.
8. Differentiate between zero-order and first-order reactions.
In a zero-order reaction, the rate is independent of the concentration of reactants (rate = k). In a first-order reaction, the rate is directly proportional to the concentration of one reactant (rate = k[A]). The unit of the rate constant also differs for each reaction order.
9. What is the significance of the half-life of a reaction?
The half-life (t1/2) of a reaction is the time required for half the reactant to be consumed. For a first-order reaction, the half-life is independent of initial concentration and given by t1/2 = 0.693/k.
10. What is the Arrhenius equation?
The Arrhenius equation relates the rate constant (k) to temperature (T) and activation energy (Ea):
k = A e-Ea/RT
where A is the frequency factor, R is the gas constant, and T is the temperature in Kelvin.
11. How is the rate constant affected by changing the temperature of a reaction?
An increase in temperature increases the rate constant (k) exponentially, as shown by the Arrhenius equation. Higher temperature results in more reactant particles possessing energy greater than or equal to the activation energy, leading to an increased reaction rate.
12. How can you determine the order of a reaction experimentally?
The order of a reaction can be determined using:
1. Initial rate method - measuring initial rates with varying concentrations.
2. Integrated rate law plots - plotting concentration vs. time data for zero, first, or second order and finding which provides a straight line.
3. Half-life method - analyzing the dependency of half-life on initial concentration.
