We’re being asked to determine which statement regarding half-lives is/are correct.

**Let’s analyze each statement:**

**I. In a second-order decay process, t _{1/2} of a 10 mM solution will be 10-times faster (i.e. t_{1/2} is shorter) than that for a 1 mM solution.**

*Recall the equation for a second-order half-life:*

Consider the half-life t_{1/2} decay of a compound. Which of the following statements regarding half-lives is/are correct?

I In a second order decay process, t_{1/2} of a 10 mM solution will be 10-times faster (i.e. t_{1/2} is shorter) than that for a 1 mM solution.

II In a first order decay process, t_{1/2 }of a 10 mM solution will be 10-times faster than that for a 1 mM solution.

III In a zeroth order decay process, t_{1/2} of a 10 mM reactant solution will be 10-times faster than that for a 1 mM solution.

A. All statements are correct

B. Only statements I and II are correct

C. Only statements II and III are correct

D. Only statement I is correct

E. Only statement III is correct
