Q. For a first-order reaction, the correct relation between concentration and time is:

प्रथम-क्रम प्रतिक्रिया के लिए, एकाग्रता और समय के बीच सही संबंध है:

[A] = [A]₀e⁻ᵏᵗ
[ए] = [ए]⁻ᵏᵗ

[A] = [A]₀ - kt
[ए] = [ए]₀ - केटी

1/[A] = 1/[A]₀ + kt
1/[ए] = 1/[ए]₀ + केटी

[A] = kt + [A]₀
[ए] = केटी + [ए]₀

First-order kinetics equation:

[A] = [A]_0 e^{-kt}
