|
What are the four factors that can affect reaction rates?
|
-The physical state of the element
-the concentrations of the reactions -the temperature at which the reaction occurs -the presence of a catalyst |
|
|
What is the common unit for reaction rates?
|
M/s
(Molarity per second) |
|
|
How is the instantaneous rate found?
|
By looking at a concentration vs. time graph, one can determine the instantaneous rate by the slope at the point of interest
|
|
|
Rate Law
aA+ bB-> cC+dD |
Rate=k[A]^m[B]^n
|
|
|
What order reaction is
Rate=k[NH4+][No2-] |
2
Because the exponent of both NH4+ and NO2- are 1 1+1=2 |
|
|
Units of rate=(units of rate constant)(units of concentration)^2
|
Units of rate constant=
units of rate/(units of concentration)^2=Ms^-1/M^2= M^-1s^-1 |
