Question

the half life period of zero order reaction is 10 minutes if its initial concentration of reactant is increased by four times then its half life period will be​

Answer 1

Explanation:

Zero order have zero dependence of the rate of reaction on the starting amount of reactant. So the rate if loss of reactants is a straight line. That means if it takes 10 minutes to use up half of a 1M solution it till take 20 min to use up half of 2M solution.

Answer 2

The half-life period would be four times

Explanation:

• The half-Life period for a zero-order reaction is given by the equation $t_{\frac{1}{2}} = \frac{[A]_0}{2k}$

where $[A]_0$ represents the initial concentration and k is the rate constant.

• The above equation represents that the half-life is directly proportional to the initial concentration.

• Thus, when the initial concentration is increased four times, then according to the above equation, the half-life will also increase four times.

Thus, now the half-life would be four times or 40 minutes.
