|
|
Keq formula for reversible reaction |
Kforward/Kreverse |
|
|
Collision theiry |
Rate of reaction is proportional to the number of collisions/second |
|
|
Exothermic reactions are |
Spontaneous Have -ΔH and -ΔG |
|
|
Endothermic reactions are |
Non-spontaneous +ΔG and +ΔH |
|
|
What’re the 4 factors that affect reaction rate? |
1.) concentration of reactants 2.) temperature 3.) medium 4.) catalysts |
|
|
Transition states are located at which part of a graph? |
The top of energy barriers |
|
|
If the Ea of the forward reaction is smaller than the Ea of the reverse, what kind of reaction was it? |
Exothermic |
|
|
Reaction quotient (Q) formula? |
Q = prod/react |
|
|
How do you know of equilibrium hasn’t been reached? |
If Qeq Spontaneous Proceeds in reverse |
|
|
If a plan has exceeded equilibrium, how is it indicated? |

|
|
Le’Chateliers principle states |
A system to which stress is applied shifts to relieve applied stress |
|
|
Adding reactants or removing products causes |
Qeq |
|
|
Removing reactants or adding products causes |
Q>Keq |
|
|
In other words, Le’Chateliers principle means |
The system reacts in the direction away from added species or toward removed species |
|
|

The direction with lower total moles |
|
|
What does temperature affect and not affect |
Changes Keq Doesn’t change Q |
|
|
If ΔH is positive, it’s seen as a |
Reactant |
|
|
If ΔH is negatives, it’s viewed as a |
Product |
