Bas_tet [7]

Answer:

This exercise is incomplete, missing the value of k (decay constant), which is equal to 4x10⁻⁸s⁻¹ at 25°C

The answer is 0.549 years

Explanation:

Given:

first order of reaction

k = 4x10⁻⁸s⁻¹

For a first order of reaction, the half-life time for the degradation of DDT is equal to:

$t=\frac{0.693}{k} =\frac{0.693}{4x10^{-8} } =17325000s=0.549years$
