  1. Kinetics Concept Equations Quiz- use your equation sheet For the reaction 2A + 2B  3C Assume A is first order and B is first order 1. Write the (stoichiometric) rate equation 2. What is the overall reaction order? 3. Write the rate law 4. Write the integrated rate law for species A 5. Which variable/symbol do we use to signify the derivate at time 0? 6. Rearrange the integrated rate law for this reaction to solve for [A]t. Bonus: Write the half life equation for species A

  2. 1. In the reaction: N2O5 N2O4 + O2 Is first order with respect to N2O5. The rate constant is 6.22 x 10-4s-1 a. If the initial concentration is 0.100M, how many minutes will it take to drop to 0.0100M? b. What is the half life? 2. In the reaction NOCl  NO + Cl, The reaction is second order. The rate constant is 0.020 L mol-1 s-1 a. If the initial concentration is 0.050M, what will be the concentration after 30 minutes? b. What is the half life? 3. Radioactive Iodine-131 has a half life of 8.0 days and the rate of decay does not matter due to the amount of initial Iodine.. A. What will the concentration be after 24.0days? (this should be easy) B. What will the concentration be after 30 days? (solving this problem requires the use of 2 equations) 4. In the reaction HI  H2 + I2, the reaction is 2nd order and k= 0.079 _____ with a starting concentration of 0.050M? A. what should the units of k be? B. What is the half-life of this reaction? C. what would happen to the half life if the initial concentration was 0.12M?
