Question 1

In aqueous solution, hypobromite ion, BrO-, reacts to produce bromate ion, BrO3-, and bromide ion, Br-, according to the following chemical equation:



A plot of 1/[BrO-] vs. time is linear and the slope is equal to 0.056 L mol-1 s-1. If the initial concentration of BrO- is 0.80 mol L-1, how long will it take one-half of the BrO- ion to react?
◦ 4.5 × 10-2 s
◦ 22 s
◦ 12 s
◦ 7.1 s

Question 2

The second-order reaction 2Mn(CO)5 → Mn2(CO)10 has a rate constant equal to 3.0 × 109 L mol-1 s-1 at 25 °C. If the initial concentration of Mn(CO)5 is 2.0 × 10-5 mol L-1, how long will it take for 90.% of the reactant to disappear?
◦ 6.0 × 103 s
◦ 1.5 × 10-4 s
◦ 6.7 × 10-16 s
◦ 7.4 × 10-15 s
