Zero-order reaction is a chemical reaction wherein the rate does not vary with the increase or decrease in the concentration of the reactants. Therefore, the rate of these reactions is always equal to the rate constant of the specific reactions (since the rate of these reactions is proportional to the zeroth power of reactants concentration).

⠀⠀⠀⠀⠀⠀⠀⠀Half-Life of a Zero Order Reaction :

The timescale in which there is a 50% reduction in the initial population is referred to as half-life. It can be noted from the equation given above that the half-life is dependent on the rate constant as well as the reactant's initial constration.

Answer 2

$\huge\fbox\pink{Zero order reaction :}$

The reaction in which the reaction rate is independent of the reactants is called zero order reaction.

Some examples

2HI ------- > H2 + I2

2NH3 ------> N2 + 3H2

$\huge\fbox\pink{Half life period :}$

= a/2k where a = initial concentration.

Hope it helps you!!!
