NEET Chemistry Rate of Reaction MCQ Question
For a first-order reaction, the half-life is 0.693/k. If the rate constant k is 0.1 s^-1, what is the half-life of this reaction?
6.93 s
0.693 s
6.93 min
0.693 min
Correct Answer
Detailed Explanation
The half-life for a first-order reaction is given by t1/2 = 0.693/k. Substituting k = 0.1 s^-1, we get t1/2 = 0.693/0.1 = 6.93 s.
