1
In Kinetics, the formula to work out temperature for a reaction is:
T=∆H/∆S
2
Pauli's exclusion principle:
Can't have the same set of quantum numbers
3

mol l-1 s-1
11
1st order units are
s-1
12
2nd order units are
mol-1 l s-1
13
3rd order units are

14
To work out k, the formula is
k = rate/ [A][B]
15
The slow step shows the reactant dependant on the reaction so if a reactant isnt there will it be in the rate equation?
no
16
Order of reaction can be worked out from the slow or fast step?
SLOW
17
Anthing burned is always: endo or exo
Exothermic
18
Why is combustion exothermic?
Change of state increases disorder
19
What is the only thing that can affect the equilibrium constant?
Temperature!!!
20
Does increasing the concentration of products or reactants in the equilibrium constant do anything?
NAW, only temperature
21
In evaporation reactions, ∆H is
positive
22
In evaporation reactions, ∆S is
Positive
23
If ∆G is negative then equilibrium lies to the
RHS
24
∆G is known as Gibb's free energy or
standard free energy
25
For a reaction to be feasible ∆S must be?
Positive
26
For a reaction to be feasible ∆G must be?
Negative
27
If K>1, then ∆G is
negative
28
If K
positive
29
If K=1 then ∆G is
0
