Multiple Choice

For the reaction aA $\rightarrow$ products, select the reaction order(s) that best fit(s) the observations.
-The reaction A $\rightarrow$ B + C is known to be zero order in A with a rate constant of 5.4 * 10^-2 mol/L • s at 25° C. An experiment was run at 25°C where [A]₀ = 3.0 *10^-3 M. What is the half-life for the reaction?

• A) 1.3 * 10¹ s
• B) 2.7 * 10^-2 s
• C) 8.1 *10^-2 s
• D) 6.2* 10⁴ s
• E) 2.8 * 10^-2 s
