Question

For a zero order reaction ______.

Options

• t_1/2 ∝ a

• `t_(1//2) prop 1/a`

• t_1/2 ∝ a²

• `t_(1//2) prop 1/a^2`

Answer 1

For a zero order reaction t_1/2 ∝ a.

Explanation:

For a zero-order reaction, the half-life t_1/2 is given by the formula:

`t_(1//2) = [R]_0/(2 k)`

Where:

[R]₀ = a (initial concentration)

k is the rate constant

This shows that:

t_1/2​ ∝ a
