chem genneral equilb

Magnitude of Keq Equal to 1

A condition where the reaction does not favor one side and significant amounts of both reactants and products are present

Magnitude of Keq Much Greater Than 1

A condition where the reaction strongly favors the products

Magnitude of Keq Much Less Than 1

A condition where the reaction strongly favors the reactants

Effect of Increasing Concentration

A stress response causing the system to shift to use up the material away from the added side

Effect of Decreasing Concentration

A stress response causing the system to shift to make more of the material toward the removed side

Effect of Increasing Volume and Decreasing Pressure

A stress response causing the system to shift to the side with more gas molecules

Effect of Decreasing Volume and Increasing Pressure

A stress response causing the system to shift to the side with fewer gas molecules

Effect of Increasing Temperature

A stress response causing the system to shift in the endothermic direction to absorb thermal energy

Effect of Decreasing Temperature

A stress response causing the system to shift in the exothermic direction to produce thermal energy

Effect of Adding a Catalyst

Has no effect on the equilibrium position because it speeds up forward and reverse rates equally

Effect of Adding a Pure Solid

Has no effect on the equilibrium position

Effect of Adding an Inert Gas at Constant Volume

Has no effect on equilibrium

Effect of Adding an Inert Gas at Constant Pressure

Causes the volume to increase, resulting in a shift toward the side with more gas molecules
