Question

For a zero-order reaction with [A]₀ = 0.1 M and k = 0.01 mol L⁻¹ s⁻¹, the time for complete reaction is:
  1. A
    10 s
    Correct
  2. B
    100 s
  3. C
    0.1 s
  4. D
    1 s

Correct answer

10 s

Explanation

For zero order: [A] = [A]₀ − kt. At completion [A] = 0: t = [A]₀/k = 0.1/0.01 = 10 s.
