JEE Mains · Chemistry · STD 12 - 3. Chemical kinetics
For the thermal decomposition of reaction AB(g), the following is constructed.
The half life of the reaction is 'x' min.
x =_________ min.(Nearest integer)
- A 5
- B 10
- C 15
- D 20
Answer & Solution
Correct Answer
(B) 10
Step-by-step Solution
Detailed explanation
\([AB]_{0}-[AB]_{t}=kt\) \(0.60-0.55=k(100)\) \(k =5 \times 10^{-4}\) Half life \(\left(t_{1 / 2}\right)=\frac{[A B]_0}{2 k}\) \(=\frac{0.60}{2 \times 5 \times 10^{-4}}\) \(=600 sec\) \(=10 min\)
