Question

Calculate the rate constant of a reaction with a given half-life.

• A. \( k = \frac{0.693}{t_{1/2}} \)
• B. \( k = \frac{1}{t_{1/2}} \)
• C. \( k = \frac{2.303}{t_{1/2}} \)
• D. \( k = \frac{0.5}{t_{1/2}} \)

Hint:

For first-order reactions, remember that the half-life depends only on the rate constant and is given by \( t_{1/2} = \frac{0.693}{k} \).
