Unit 5 Test Flashcards
Which way will the reaction proceed?
Q>Keq
Left
Which way will the reaction proceed?
Q
Right
Q=Keq
It’s already at equilibrium silly!
If pressure is increased to which side will the reaction proceed?
To the side with fewer moles of gas
If the pressure on a system is decreased which side will the reaction shift to?
To the side with more moles of gas
If you add moles of one species to one side of the reaction which direction will the reaction shift
To the opposite side
If you remove moles of a certain species to which side will the reaction proceed
To the side that had the species removed
Reactants - products + heat
Negative H° value
Exothermic. Add or remove heat from products side
Reactants + heat- products
A positive H° value
Endothermic
Add or remove heat from reactants side
Is A value of G that is less than 0 thermodynamically favored
Yes
Is a value of G that is more than 0 thermodynamically favored?
No
An exergonic reaction is when G is…
Less than 0
Keq is greater than 1
An endergonic reaction is when G is…
More than 0
Keq<1
The constant for G is…(hint it starts with 8)
8.314J/mol x K
The constant in a partial pressure equation is
.0821
