Answer:
The ratio of half-lives for a reaction with starting concentrations of 0.05M and 0.01M, t1/2 (0.05M) / t1/2 (0.01M) = 1, if a reaction is known to be first order.
Explanation:
- For a first- order reaction:
the half-life of the reaction is constant and does not depend on the value of the initial concentration.
half-life (t1/2) = 0.693/k,
where, k is the rate constant of the reaction.
So, half;life of first-order reaction is constant whatever the initial concentration.
So the ratio of t1/2 (0.05M) / t1/2 (0.01M) = 1
