question 75

Multiple Choice

Which of the following equations shows the correct relationship between the half-cell of a nuclide and the radioactive decay rate constant?

• A)ln \(\frac { N _ { t } } { N _ { 0 } }\) = -\(\frac{k}{t}\)
• B) \(\frac { N _ { t } } { N _ { 0 } }\) = - ln\(\frac{k}{t}\)
• C) \(t 1 / 2\) = 0.693 × k
• D) \(t 1 / 2\) =\(\frac { k } { 0.693 }\)
• E) \(t 1 / 2\) =\(\frac { 0.693 } { k }\)
