- \(t_{1/2}\)
- \(t_{3/4}\)
- \(t_{2/3}\)
- Data insufficient to predict
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: At the point of intersection, [A]=[B].
Step 2: For reaction A→ B, this occurs when half of A has reacted.
Step 3: Thus the time corresponds to half-life t₁/2.
