Question

Calculate half-life period of life order reaction whose rate constant is 200 sec^–1

Options

• 4.265 × 10^–3 sec.

• 3.465 × 10^–3 sec.

• 2.562 × 10^–2 sec.

• 2.111 × 10^–2 sec.

Answer 1

3.465 × 10^–3 sec.

Explanation:

Half-life period `t_(1/2) = 0.693/K`

`0.693/(200 sec^-1)` = 3.465 × 10^–3 sec
