Question:medium
Half life of a first order reaction is $900\text{ minute}$ at $400\text{ K}$, find its half life at $300\text{ K}$ ?
$\left( \frac{\text{E}_\text{a}}{2.303\text{R}} = 1.3056 \times 10^3 \right)$

$\left( \frac{\text{E}_\text{a}}{2.303\text{R}} = 1.3056 \times 10^3 \right)$
$\left( \frac{\text{E}_\text{a}}{2.303\text{R}} = 1.3056 \times 10^3 \right)$
Show Hint
Temperature down $\rightarrow$ Rate down $\rightarrow$ Half-life up.
