With increase in initial concentration, the fractional conversion of a first order reaction in a given time___________________?
Correct answer: C. Remain constant
- A. Increases
- B. Decreases
- C. Remain constant
- D. Unpredictable
Explanation
For a first-order batch reaction, the integrated relation is −ln(1 − X) = kt, so conversion at a fixed time depends on k and t, not on the initial concentration. Thus the fractional conversion remains constant.
