The rate of disintegration of fixed quantity of a radioactive element can be increased by

Question

The rate of disintegration of fixed quantity of a radioactive element can be increased by (A) increasing temperature (B) increasing the pressure (C) chemical reaction (D) it is not possible

Tardigrade Admin · Accepted Answer

In radioactivity, rate of disintegration cannot be increased.
Rate of disintegration

\frac{d N}{d t} = - λ N λ

, decay constant,

N =

initial amount.
If

N

is fixed.
Then,

\frac{d N}{d t} =

constant Rate of disintegration does not depend upon external fraction.

Q. The rate of disintegration of fixed quantity of a radioactive element can be increased by

increasing temperature

increasing the pressure

chemical reaction

it is not possible

In radioactivity, rate of disintegration cannot be increased. Rate of disintegration dtdN​=−λNλ, decay constant, N= initial amount. If N is fixed. Then, dtdN​= constant Rate of disintegration does not depend upon external fraction.

In radioactivity, rate of disintegration cannot be increased.
Rate of disintegration $\frac{d N}{d t} = - λ N λ$ , decay constant, $N =$ initial amount.
If $N$ is fixed.
Then, $\frac{d N}{d t} =$ constant Rate of disintegration does not depend upon external fraction.
