Question

4. Complete the table given below

Answer 1

To solve this formula, we can simply use the formula of half-life of a radioactive substance to calculate the decay rate.

The disintegration constant or decay rate is calculated as 0.385min^-1

Half-Life

The half-life of a radioactive substance is defined as the time taken for the initial mass of the substance to reach half it's starting mass.

The formula is given as

$T_\frac{1}{2} = \frac{\ln2}{\lambda}$

Let's substitute the value into the equation and solve through

$T_\frac{1}{2} = \frac{\ln2}{\lambda} \\\lambda = \frac{\ln2}{T_\frac{1}{2} } \\\lambda = \frac{0.693}{1.8} \\\lambda = 0.385$

The disintegration constant or decay rate is calculated as 0.385min^-1
