When the initial concentration of a zero order reaction is doubled, the half-life of the reaction is:
- A doubled
- B tripled
- C halved
- D not changed
Answer & Solution
Correct Answer
(A) doubled
Step-by-step Solution
Detailed explanation
For a zero order reaction, the half-life is given by the expression: \(t_{1/2} = \dfrac{[A]_0}{2k}\) where \([A]_0\) is the initial concentration and \(k\) is the rate constant. This shows that the half-life is directly proportional to the initial concentration (…
