The reaction A $\rightarrow$ B + C is known to be zero order in A with a rate constant of 3.8 *10^-² mol/L • s at 25° C. An experiment was run at 25°C where [A]₀ = 2.2 *10^-³ M. What is the rate after 6.8 minutes?

Question

Quizplus · Accepted Answer

Since the reaction is zero order in A, the rate of the reaction is independent of the concentration of A. Therefore, the rate constant remains the same regardless of the concentration of A. Thus, the rate after 6.8 minutes would still be 3.8 F1F1F1S1•F1F1F10 10^-² mol/L • s, which is option B.
