Interpretation:
If NO2 is allowed to decompose at 650 K and the concentrations drops to 0.0010 M in a particular time frame.
Concept introduction:
The thermal decomposition of gas phase reactions can be extremely complex due to a large number of parameters, a variety of possible intermediates, and an overlap in thermal decomposition traces. It is determine the experimental method of the activation energy is particularly difficult when several possible reaction pathways coexist in the thermal decomposition.
To determine:
The time taken for NO2 concentration to drop to 0.0010 M in the reaction
Data for gas phase decomposition of NO2 is:
Temperature (K) | Initial [NO2] | Initial rate of decomposition of NO2 (M/s) |
600 | 0.0010 | 5.4×10-7 |
600 | 0.0020 | 2.2×10-6 |
700 | 0.0020 | 5.2×10-5 |
