First Order Reaction

The half-life...

Question

The half-life time of reaction: $A \to p r o d u c t s$ , is the time during which half of A changes into products. For a first-order, $t_{1 / 2} = x / k$ . $1000 x$ is

Solution

The half-life time of reaction: $A \to p r o d u c t s$ , is the time during which half of A changes into products.
For a first-order, $t_{1 / 2} = 0.693 / k = x / k$ .
Hence, $x = 0.693$
$1000 x = 1000 \times 0.693 = 693$ .
