Q. For a second-order reaction A → products, the half-life is:

दूसरे क्रम की प्रतिक्रिया ए → उत्पादों के लिए, आधा जीवन है:

Independent of [A]₀
[ए]₀ से स्वतंत्र

Directly proportional to [A]₀
[ए]₀ के सीधे आनुपातिक

Inversely proportional to [A]₀
[ए]₀ के व्युत्क्रमानुपाती

Proportional to √[A]₀
√[A]₀ के समानुपाती

For second-order:

t_{1/2} = \frac{1}{k[A]_0}

So half-life decreases as initial concentration increases.
