The rate of radioactive decay can not be changed with environmental factors, causing disposal issues for countries with large scale nuclear power plants. Radioactive rate laws are characterized by which of the following?

Zero order reaction because the rate is independent of the substance.

Solution

The correct option is B First order reaction because the rate depends only on the identity of the substance.
For radioactive decay, Rate $= \frac{- d N}{d t} = K N$
$∴$ Rate depends only on number of particles of radioactive element.
$∴$ It is a first order reaction.
