The decay of a radioactive element follows first order kinetic. Thus, a)Half-life period `= a` constant`//K`, where `K` is decay is independent of temperature b)The rate of decay is independent of temperature c)The rate can be altered by changing chemical conditions d)The element will be completely transformed into new element after expiry of two half-life period

Options

A. Half-life period = constant/k, where k is the decay constant
B. Rate of decay is independent of temperature
C. Rate can be changed by changing chemical conditions
D. The element will be completely transformed into a new element after expiry of two half-life period

Answer

A

Explanation

For `1^(st)` order `t_(1//2) = 0.693 K^(-1)`. Rate of decay is independent of temperature.
