Question:
First order reaction (A→P) with slopes mA, mB, mC at points A, B, C. Identify correct order.
First order reaction (A→P) with slopes mA, mB, mC at points A, B, C. Identify correct order.
Show Hint
For first-order reactions, slopes are proportional to concentration; higher concentration → steeper slope.
Updated On: Mar 6, 2026
- mA = mB = mC
- mA>mB>mC
- mC>mB>mA
- mB>mC>mA
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
For first-order reactions, slope of [A] vs time = -k[A]. Higher [A] → larger slope. So slope decreases with decreasing [A]: mA>mB>mC.
