CHEM 1212 Practice This is only to help you prepare for the upcoming test. Of course you should be reviewing and using all available resources for your preparation. 1. Determine the rate law when given the following data (at 25 Celsius): 3 A( aq ) + 2 B( aq ) 4 C( aq ) Rate mol/L-s A mol/L B mol/L 0.00021 0.150 0.120 0.00336 0.150 0.480 0.00021 0.450 0.120 0.00336 0.450 0.480 2. Solve for the rate constant k for the above rate law, including units for k. 3. What is the rate of the reaction if [B] is 0.35M? [include units in your answer] 4. Write an equation that relates [B] t to k, t and [B] 0 5. If the initial concentration of [B] is 0.35 M, what is the concentration of [B] 18 ? 6. What is the half-life of [B] in this reaction? 7. Would this be a suitable mechanism for this reaction? 2 B 3 D <slow> 3 A + 3 D 4 C <fast>
