U3, S2: Equilibrim Stressors and Graphs

What are the 4 stresses that shift equilibriums?

Adding/removing chemicals, changing pressures, changing volumes, and changing temps

If a stressor was placed on a system, but the graph remained unchanged, what occured?

A catalyst or inert gas (a noble gas) was added

If a product was added, which way will equilibrium shift?

To the reactant side (more products can react to make more reactants)

If a reactant was added, which way will equilibrium shift?

To the product side (more reactants can react to make more products)

What stressor causes K (constant) to change?

Temperature change

If there is an increase in volume (decrease pressure), which way will equilibrium shift?

To the side with the most moles

If there is a decrease in volume (increase pressure), which way will equilibrium shift?

To the side with the least moles

What does a temperature change look like on a graph?

All chemicals have a gradual change

What does a pressure/volume change look like on a graph?

All chemicals have a sudden, sharp change

What does a concentration change look like on a graph?

Only one chemical has a sudden change
