Reaction Rates (Sections)
The rate of disappearance of HCI was measured for the following reaction:
CH30H(ag) + HCI(aQ) → CH3CI(aQ) + H20(/)
The following data were collected:
(a) Calculate the average rate of reaction, in M/s. for the time interval between each measurement, (b) Calculate the average rate of reaction for the entire time for the data from t = 0.0 min to t = 430.0 min. (c) Which is greater, the average rate between t = 54.0 and t = 215.0 min. or between t = 107.0 and t = 430.0 min? (d) Graph [HCI] versus time and determine the instantaneous rates in M/min and M/s at t = 75.0 min and t = 250 min.
Notes on Chemistry 142 General Chemistry 2015 – 2016 Notes on atoms, molecules & ions and Quantum Mechanics & Atomic Theory:- 1. Wave particle duality behave more like particles. Bohr’s model of a hydrogen atom 2. motion when subjected to a constraining potential 3. System – the part of the universe we are interested in 4. Surroundings – the universe 5. potential energy of molecules 6. Electrostatic – intermolecular attractions and chemical bonds. (Molecular potential energy) 7. Chemical internal energy: Internal energy of a chemical system includes kinetic and 8. Wave mechanics: An electron can adopt only certain standing wave patterns of 9. Bright spots: constructive interference
