Question
For the following reaction 3 experiments have been run and the data collected is in the following table @ 35 degrees Celsius
2 NO2F(g) ---> 2 NO2(g) + F2(g)
| Experiment | [NO2F], M | Rates, M/s |
| 1 | 0.263 | 0.168 |
| 2 | 0.349 | 0.223 |
| 3 | 0.421 | 0.269 |
a) How long will it take for a 65% NO2F solution to become a 31% NO2F solution @35 degrees Celsius?(Hint: Use mass ratios and assume ~1g/ml for density of solutions to get you started)
b) It has been determined that at 75 degrees Celsius the rate constant is 1.046 s-1. Calculate the activation energy for the decomposition of NO2F. [Hint: ]ln?1?2=?a?(1?2―1?1)
c) What is the half-life of a 35% solution of NO2F @ 35 degrees Celsius?
