At any point during a reaction, we can measure the concentrations of all of the reactants and products and calculate the ____________ ____________.
reaction quotient
When K < Q, which was does the reaction go?
To the left, towards the reactants (too much product)
When K = Q, the reaction is at ____________ and the forward and reverse rates are ________.
equilibrium, equal
When K > Q, which way does the rxn go?
Towards the product, forward rate
The larger the value of Keq, the farther to the ________ the equilibrium position.
right
If equilibirum constant for a reaction written in one direction is Keq, the equilibirum constant for the reverse is what?
1/Keq
A reaction that strongly favors products will have what eq exponent?
a large, positive one
If pressure is increased, the reaction will move toward which direction?
Whichever side has less moles of gas
If a reaction is ____________, heat functions as a reactant. If exothermic, heat is a ____________.
endothermic, product
At lower temperatures (with smaller heat transfer), a ____________ product is formed. It is formed faster.
kinetic
At higher temperatures (with larger heat transfer), a ____________ product is formed. It is more stable.
thermodynamic
Which forms faster, kinetic or thermodynamic products? Why?
Kinetic products; the free energy that must be added for the kinetic pathway is lower than that of the thermodynamic pathway See p212
