Kenetics 2 Flashcards
What effects a sequential reaction
The rate of k1 compared to k2
Give an example of sequential reaction
Injection of fluorescence into the skin and the removal
What is the steady state approximation
That an intermediate transition state concentration is effectively zero
If you let a reaction complete what equations are obtained
K1/k-1=b infinitely / a infinitely
What is the lindemann theory
The assumption that an intermediate existed in order to find a rate equation
What steps does a chain reaction include
Initiation
Propagation
Termination
What is chain length
Rate prop/ rate termination
Why do some reactions explode
In chain reaction when the product is reactive and re enteres the cycles
What are the 2 forms of removal from a chain reaction
Wall removal and gas phase termination
What is bimolecular theory
The breaking down of the 2 points that are a molecule must collide and also have sufficient energy
What is the k bimolecular equation
= sigma v e^ ea/rt
What is transition state theory
Application of thermodynamics to a transition state
What is the eyring equation
It includes the transmission term, universal frequency factor, and entropy
If A is positive what does this indicate
Entropy is positive therefore transition state is less well ordered and A is greater than universal frequency factor
What do potential energy diagrams show
Products and reactant valley and saddle point which is the transition state
