Question: What is the integrated rate law for a zero-order reaction?

Options:

1. [A] = [A]0 - kt
2. [A] = [A]0 + kt
3. [A] = [A]0e^(-kt)
4. [A] = kt + [A]0

Correct Answer: [A] = [A]0 - kt

Solution:

For a zero-order reaction, the integrated rate law is [A] = [A]0 - kt, indicating that the concentration decreases linearly with time.
