a) independent of the concentration
b) inversaly proportional to the initial conc
c) inversely proportional to conc.
d) directly proportional to the conc.
The answer is b.

Question

Answer

Check half life =expectation of second order reaction

Answer

B

Answer

Half life is invesely proportinal to conc to power of (n-1) where n is order of reaction for sencond order half life is inversely proportional to conc

Answer

It should be c

The

half life

of a

second order reaction is inversely proportional

to the

initial concentration

of the reactants(google search)

Answer

Ans must be C it is directly proportional for 0 order reactions.

Answer

Explanation:

Second Order Reaction:
A second order reaction is a chemical reaction in which the rate of reaction is directly proportional to the square of the concentration of one of the reactants.

Half-life Period:
The half-life period of a reaction is the time required for the concentration of a reactant to decrease to half of its initial concentration.

Inversely Proportional to the Initial Concentration:
In a second order reaction, the half-life period is inversely proportional to the initial concentration of the reactant. This means that as the initial concentration increases, the half-life period decreases, and vice versa.

Explanation:
- When the initial concentration of the reactant is high, the rate of the reaction is also high. This leads to a faster decrease in concentration over time, resulting in a shorter half-life period.
- Conversely, when the initial concentration of the reactant is low, the rate of the reaction is slower. This leads to a slower decrease in concentration over time, resulting in a longer half-life period.
Therefore, the half-life period of a second order reaction is inversely proportional to the initial concentration of the reactant.

Answer

The correct answer is Option B.

Relation between half-life period of a reaction and initial concentration is as follows:

For first order reaction (Half life α a⁰ )
For second order reaction (Half life ∝
1/a)
For third order reaction (Half life ∝ 1a²)
