Question
For the chemical reaction A + B → C, a plot of [A] versus time is found to give a straight line with a negative slope. What is the order of reaction?
Correct Answer
Option A is the correct answer.
Detailed Explanation
For zero-order reactions, the integrated rate law is [A] = -kt + [A]₀. A plot of [A] vs. time gives a straight line with slope -k.
Hint
Recall the integrated rate laws and which plot gives a straight line for each order.
