Question 1

The reaction 3NO → N2O + NO2 is found to obey the rate law, Rate = k[NO]2. If the first half-life of the reaction is found to be 2.0 s, what is the length of the fourth half-life?

◦ 2.0 s
◦ 4.0 s
◦ 8.0 s
◦ 12.0 s
◦ 16.0 s

Question 2

The reaction A → B + C is known to be zero order in A with a rate constant of 5.0 × 10–2 mol/L·s at 25°C. An experiment was run at 25°C where [A]0 = 1.0 × 10–3M. What is the concentration of B after 5 × 10–3 sec?
Reference: Ref 12-12

​

​


◦ 5.0 × 10–5M
◦ 5.0 × 10–4M
◦ 7.5 × 10–4M
◦ 2.5 × 10–4M
◦ None of these are correct.
