Ppt Reaction Rates Powerpoint Presentation Free Download Id 6516140 Students know the rate of reaction is the decrease in concentration of reactants or the increase in concentration of products with time. • 8. b. students know how reaction rates depend on such factors as concentration, temperature, and pressure. • 8. c. students know the role a catalyst plays in increasing the reaction rate. • 8. d.*. Reaction rates • consider the decomposition of n2o5 to give no2 and o2: 2 n2o5 (g) 4 no2 (g) o2 (g) reaction rates. rate law & reaction order • rate law: shows the relationship of the rate of a reaction to the rate constant and the concentration of the reactants raised to some powers. • for the general reaction: aa bb cc dd rate = k.
Ppt Reaction Rates Powerpoint Presentation Free Download Id 6516140 The rate of the reaction is given by: definition of reaction rates • then, in a given time interval, dt , the molar concentration of o2 would increase by d [o2]. • this equation gives the average rate over the time interval, dt. • if dt is short, you obtain an instantaneous rate, that is, the rate at a particular instant.
