Question 1

The half-life for the second-order decomposition of HI is 15.4 s when the initial concentration of HI is 0.67 mol L-1. What is the rate constant for this reaction?
◦ 2.2 × 10-2 L mol-1 s-1
◦ 4.5 × 10-2 L mol-1 s-1
◦ 3.8 × 10-2 L mol-1 s-1
◦ 9.7 × 10-2 L mol-1 s-1
◦ 1.0 × 10-2 L mol-1 s-1

Question 2

The rate constant for a second-order reaction is 0.54 L mol-1 s-1. What is the half-life of this reaction if the initial concentration is 0.27 mol L-1?
◦ 2.0 s
◦ 5.0 s
◦ 0.25 s
◦ 6.9 s
◦ 1.3 s
