Document Summary

You should be able to solve q 1, 2. Remember: solving 2 questions per day is better than all problems in one day! Kinetics is concerned with the reaction progress or pathway. How do we get from the initial state (reactants) to the final state (products). Rate of rxn time interval change in concentration. The ve sign should make sense as no2 is being consumed. Reaction rate is always a +ve quantity ! To get the rate you need to divide by the time. Rxn rate is specific to a rxn (you need a balanced rxn) and therefore is stoichiometry dependent. Rate of formation or rate of disappearance are not specific for a reaction and are stoichiometry independent. Rates of formation or disappearance are not necessarily equal to the reaction rate. In general aa + bb dd +ee. [b] b t = [d] d t = [e] e t.
