Question
A zero-order reaction has rate constant k = 0.02 mol/L/s and initial reactant concentration [A]0 = 0.5 mol/L. Calculate the time (in seconds) for the reaction to go to completion (when [A] reaches zero), rounded to 2 decimal places.
✓ Verified answer: 25checked by our engine — not a guess
Step-by-step solution
For zero order, [A] = [A]0 - kt. At completion [A] = 0, so t = [A]0/k = 0.5/0.02 = 25 s. Final answer: 25.0
