NEET Chemistry Activation Energy MCQ Question
If the rate constant for a first order reaction is 60 s⁻¹, how long will it take for the concentration of the reactant to decrease to 1/16th of its initial value?
0.0578 s
0.1156 s
0.2312 s
0.3468 s
Correct Answer
Detailed Explanation
For a first order reaction, the time taken to reduce to 1/16th of the initial concentration involves using the formula t = (ln 16) / k, where k = 60 s⁻¹.
