Rate constant
|
Coefficient K, independent of the concentrations taking part in the reation
Quantifies the speed of the reaction |
|
Rate law
|
Is an equation that expresses the rate of reaction in terms of the molar concentration in the overall reaction
|
|
Isolation Method
|
All the reactants are in excess except one
|
|
Order of Reaction
|
Is the exponent to when its concentration term in the rate equation if raised for individual components, or the sum of individual reactants for the whole equation
Could be zero, negative or fractional |
|
Activation energy
|
Minimum energy particles are required to react
|
|
Reaction Mechanism
|
Step by step process of reactions by which an overall chemical change occurs
|
|
Chemical Kinetics
|
Involves the rate of reactions to form products from reactants and the elementary steps for reactions to take place
|
|
Ways to measure the rate of a reaction...
|
pressure measurements
spectrometry conductivity measurement pH measurement polarimetry |
|
Stoichiometry is
|
concentration of reactants and products
|
|
Reaction rate
|
Number of moles of reaction per unit time
|
|
How can the instantaneous rate be determined?
|
Graph of concentration against time
|
|
Why is it more beneficial to use an integrated rate method rather than an initial rate method?
|
Initial rate method does not tell us about the whole course of the reaction
|
|
What are elementary reactions?
|
Many reactions which occur in a series of steps
|
