JEE Mains · Chemistry · STD 12 - 3. Chemical kinetics
A \(\rightarrow\) products (First order reaction).
Three sets of experiment were performed for a reaction under similar experimental conditions.
Run \(1 \Rightarrow 100 mL\) of 10 M solution of reactant A
Run \(2 \Rightarrow 200 mL\) of 10 M solution of reactant A
Run \(3 \Rightarrow 100 mL\) of 10 M solution of reactant A+ 100 mL of \(H _2 O\) added.
The correct variation of rate of reaction is:
- A Run 1 = Run 2 = Run 3
- B Run 3 < Run 1 = Run 2
- C Run 3 < Run 1 < Run 2
- D Run 1 < Run 2 < Run 3
Answer & Solution
Correct Answer
(B) Run 3 < Run 1 = Run 2
Step-by-step Solution
Detailed explanation
For \(1^{st}\) order reaction, \(Rate=k[A]\). with decrease in concentration of A , rate of reaction decreases.
