Definition
|
|
Term
| a state of balance in which the rates of the forward and reverse reactions are equal; no net change in the amount of reactants and products occurs in the chemical system |

|
|
Term
| the relative concentrations of reactants and products of a reaction that has reached equilibrium; indicates whether the reactants or products are favored in the reversible reaction |

|
Term
| what kinds of stresses in a chemical system upset the equilibrium? |
|
Definition
| changes in the concentration of reactants or products, changes in temperature, and changes in pressure |
|
|
Term
| (Keq) the ratio of product concentrations to reactant concentrations at equilibrium, with each concentration raised to a power equal to the number of moles of that substance in the balanced chemical equation |
