Question 1

The reaction has the following rate law:
   
After a period of 2.7 × 103 s, the concentration of NO falls from an initial value of 2.8 × 10–3 mol/L to 2.0 × 10–3 mol/L. What is the rate constant, k?

1.5 × 10–7M–1·s–1

5.3 × 10–2M–1·s–1

3.2 × 10–1M–1·s–1

1.2 × 10–4M–1·s–1

2.6 × 10–2M–1·s–1


Question 2

The reaction 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 = 1.7 × 10–3M. The half-life for the reaction is

1.7 × 10–2s
1.7 × 102s
5.0 × 10–2 s
3.4 × 10–4s
None of these are correct.
