Chemistry-Rate of Reaction
NEET Chemistry Rate of Reaction Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): The rate of a reaction can be influenced by the initial pressure of reactants. | Reason (R): For a reaction A(g) → B(g) + C(g), the change in partial pressure of A over time can be used to determine the rate constant for a first-order reaction.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false but R is true.
Correct Answer
Option A
Detailed Explanation
The partial pressure changes in gaseous reactions are used to determine rate constants, and initial pressure affects reaction rate, as shown in the pressure data for N2O5 decomposition in the NCERT context.
