Consider the following reaction A Products This reaction is completed in 100 ~min . The rate constant of this reaction at t₁=10 min , is 10⁻² ~min ⁻¹ . What is the rate constant ( . in ⁻¹ ) at t₂=20 ~min ?

Question

Quantrex Academy · Accepted Answer

Correct answer: B. 10⁻²

For a first order reaction, rate constant does not depend upon concentration. Rate constant at t₂=20 ~min also 10⁻² ~min ⁻¹ (constant).
