After 24 hour, only `0.125" g"` out of the initial quantity of 1 g of a radioactive isotope remains behind. The half-life period of the radioactive isotope in hours is

Text Solution

Verified by Experts

The correct Answer is:
8
For every `10^@` rise of temperature, the rate of reaction is doubled. If at `20^@C`, rate = r, at `30^@C`, it will be 2 r, at `40^@C` it will be 4 r and `50^@C`, it will be 8 r.
