Determine the rate constant for the radioactive decay of 87Rb.
Interpretation:
The rate constant for the radioactive decay of rubidium-87 has to be calculated.
Concept Introduction:
Radiocarbon dating: The dynamic equilibrium exists in all living organism by exhaling or inhaling, maintain the same ratio of
Half-life period: The time required to reduce to half of its initial value.
Formula used to calculate rate constant:
The quantity of a radio-element which disappears in unit is directly proportional to the amount present.
Here;
k = Rate constant; Half-life of Rubidium-87 = 48.8 billion years.
