Question

Time required to decompose half of the substance for n^th order reaction is inversely proportional to ______.

Options

• a^{n + 1}

• a^{n − 1}

• a^{n − 2}

• aⁿ

Answer 1

Time required to decompose half of the substance for n^th order reaction is inversely proportional to a^{n − 1}.

Explanation:

For an n^th order reaction (where n ≠ 1), the half-life is given by:

`t_(1//2) prop 1/([A]_0^(n - 1))`

This means the time required to decompose half of the substance is inversely proportional to the (n − 1)^th power of the initial concentration.
