EXPERIMENT 2
Title Of The Experiment: Determination Of The Activation Energy For The Reaction Of Bromide And Bromate Ions In Acid Solution
Objectives : 1.To understand the chemistry of activation energy. 2. To determine the activation energy for the reaction of bromide and bromated ions in acid solution.
Result:
Temperature,T(K) | Temperature,T(C°) | 1/Temperature, K-1 | Time taken,t(sec) | Log t | 348 | 75 | 2.874 x 10-3 | 19.32 | 1.286 | 338 | 65 | 2.959 x 10-3 | 21.69 | 1.336 | 328 | 55 | 3.049 x 10-3 | 46.59 | 1.668 | 318 | 45 | 3.144 x 10-3 | 70.06 | 1.845 | 308 | 35 | 3.247 x 10-3 | 195.47 | 2.291 | 298 | 25 | 3.356 x 10-3 | 346.63 | 2.540 | 288 | 15 | 3.472 x 10-3 | 741.00 | 2.870 |
Calculation:
Finally calculate the energy of activation of the reaction (assume R = 8.314 JK-1).
Slope of graph = EA 2.303R = k
Gradient of the graph = (2.870-1.286)
