6.CI Reaction Kinetics Flashcards
1
Q
Define ‘Stoichiometric equation’
A
the sum of all reactions occurring - a multi-step reaction
2
Q
Define ‘Reaction Kinetics’
A
refers to the individual stages of a reaction
3
Q
What is the equation for the rate of reaction?
A
rate = change in conc. of reactants or products/unit time
4
Q
What is the format of a kinetic rate equation?
A
rate = K[A][B]² [A] = first order with respect to [A] [B] = second order with respect to [B]
5
Q
what is the effect of the zero order on rate?
A
it has no effect on rate
6
Q
what is the effect of the first order on rate?
A
rate directly proportional to conc.
7
Q
what is the effect of the second order on rate?
A
rate directly proportional to conc².
8
Q
Is this statement true?
you cannot predict the rate equation for a reaction based on its balanced equation
A
yes, true
