|
|
Term
do catalysts shift the equilibrium |
|
Definition
no, only speeds the rate of reaction |

Definition
energy of the reactants and products |
|
|
Term
does entropy decrease or increase from reactants to products? |
|
Definition
it depends which side has a greater number of particles |
|
|
Term
|
Definition
an indication of the relative amounts of reactants and products present at equilibrium |

|
|
Term
|
Definition
a condition in a reaction system when the rates of the forward and reverse reactions are equal |
|
|
Term
equilibrium concentration |
|
Definition
the unchanging concentrations of reactants and products in a reaction system that is in a state of equilibrium |
