AIPMT PRELIMS 2006 Chemistry Rate of Reaction MCQ Question
Type: MCQ-conceptual-Medium-Class 12
For the reaction 2A + B → 3C + D which of the following does not express the reaction rate?
A
-d[C]/3dt
B
-d[B]/dt
C
d[D]/dt
D
-d[A]/2dt
Correct Answer
Option A
Detailed Explanation
The rate of reaction is expressed as the change in concentration of reactants or products per unit time. The correct rate expressions should be proportional to the stoichiometric coefficients. Here, d[D]/dt does not match the stoichiometry of the reaction.
