Question

For a reaction, \( A \to B \), rate equation is \( r = k[A]^0 \). If initial concentration of reactant is \( a \) mol dm\(^{-3}\), find the half-life time of the reaction.

• A. \( a/k \)
• B. \( k/a \)
• C. \( \frac{a}{k} \)
• D. \( \frac{k}{a} \)

Hint:

For zero-order reactions, the half-life is directly proportional to the initial concentration and inversely proportional to the rate constant \( k \).

Answer 1

The Correct Option is C
