Second-order reaction kinetics show half-life that:

A Is constant

B Depends on initial concentration (inversely proportional)

C Depends on temperature only

D Is always 2 minutes

✓ Correct Answer: Option B

For second-order: t₁/₂ = 1/(k[A]₀). Half-life increases as concentration decreases.

💡 Why is B) the correct answer?

The correct answer to the question "Second-order reaction kinetics show half-life that:" is Option B: Depends on initial concentration (inversely proportional).

The other options — A) Is constant, C) Depends on temperature only, D) Is always 2 minutes — are incorrect for this PCAT Exam Prep question. As explained above: For second-order: t₁/₂ = 1/(k[A]₀). Half-life increases as concentration decreases.
