1.) For the reaction **X---->****Y**; rate = 0.66/min ⌈X⌉. If you start with a 0.500 M solution of **X**, what is the concentration of **X** after 1.34 min?

2.) For a reaction **X----->**** Y**; rate = 0.259/min ⌈X⌉. What is the half life for the reaction?

3.) For the reaction **X---->**** Y**; rate = 0.59/min ⌈X⌉. How many minutes will it take for the **X **concentration to fall from 1.1 M to 0.100 M.

4.) The reaction **X---->**** Y** is second in order in ** X**; with k = 1.03 (L/mol∙sec). Calculate the rate when the concentration of X = 0.868 mol/L.

5.) What is the half-live of an unstable compound if 75 % of any given amount of the substance decomposes in 8.86 hours?

- For 1,2,3 the reaction order is 1, not 0 (see measurement units for k). For 4, the measurement unit for result is L/(mol.s).
