Equilibrium Lesson 01

Reversible Reactiom

can proceed in either the forward direction or reverse direction

Forward diretion

Reactants convert to products

Reverse direction

Products convert to reactants

ΔG<0

Reaction goes in forward direction

ΔG>0

Reaction goes in reverse direction

ΔG=0

Reaction at equilibrium

Equilibrium

Most stable state of a system

Ideal ratio of product-to-reactant concentrations

Always some reactant AND product present

Reactions always proceed spontaneously in whichever direction brings them closer to _____

equilibrium

Once equilibrium is reached, concentrations become ____

constant

At the molecular level, _________ reactions still occur

Forward and reverse

At equilibrium, the forward and reverse reactions occus at ______

the same speed

Equilibrium constant

Describes the “position” of equilibrium (product-to-reactant ration) at a particular temperature

K>1

More product than reactants present at equilibrium

Product favored

K<1

More reactants than products at equilibrium

Reactant favored
