Question
A reaction is second order in reactant A with rate constant k = 0.05 L/mol/min and initial concentration [A]0 = 0.2 mol/L. Calculate the half-life of the reaction in minutes, rounded to 2 decimal places.
✓ Verified answer: 100checked by our engine — not a guess
Step-by-step solution
For a second-order reaction, t_half = 1/(k[A]0) = 1/(0.05 * 0.2) = 1/0.01 = 100 min. Final answer: 100.0
