chemistry exam 3 terms to remember

Shifting equilibrium - if you increase a reactant

It will shift to the right to products

Shifting equilibrium- if you increase products

It will shift to the left to reactants

Lower pressure , high volume

Makes the equilibrium shift to the right to products

Higher pressure, lower volume

Causes a shift to the left to reactants

Endothermic shift increase in temperature

Causes a shift to the right to products

Endothermic shift decrease in temp

Causes a shift to the left to reactions

Exothermic shift- increase in temperature

Causes shift to the left to reactions

Exothermic shift- decrease in temperature

Causes shift to the right to products

Equilibrium shift- catalyst cause to equilibrium

Catalyst has no effect on equilibrium but it does cause a faster reaction

Rate laws- first order

Rate=K[A]

Rate laws- second order reaction

Rate=K[A]²

Rate law- zero order reaction

Rate= K

First order half life rate law

Ln2/K

Second order Half life rate law

1/K[A]

0 order half-life rate law

[A]/2K
