Question

Substance A decomposes by a zeroth-order reaction. Starting initially with [A] = 2.00 M, after 150 min [A] = 0.50 M. For this reaction, what are the values and units of half-life and rate constant?

Step 1

00 M Concentration after 150 minutes (A) = 0.50 M Time (t) = 150 minutes Using the formula: k = 2.303 / t * log(A₀ / A) k = 2.303 / 150 * log(2.00 / 0.50) k = 2.303 / 150 * log(4) k = 2.303 / 150 * 0.6021 k ≈ 0.924 min⁻¹ Show more…
