- Equilibrium
- At equilibrium the amount of reactants and products stay the same. As the reactants get used up, the forward reaction slows down_and as more products are formed the reverse reaction speeds up.
- The amount of products and reactants won't be changing_this is dynamic equilibrium_can only happen in a closed system, constant temperature
- Definitions
- Homogeneous System : all reactants and products are in the same phase
- Heterogeneous system: Reactants and products are not in the same phase
- Kc is the equilibrium constant
- Only affected by temperature
- If you increase temperature you add heat the equilibrium shifts in the endothermic direction to absorb heat
- Decreases the temperature removes heat so the equilibrium shifts in the exothermic direction
- If the change means more product is formed Kc will rise. If it means less products is formed then Kc will decrease
- Kc is products on the top, reactants on the bottom, powers are the moles
- Only affected by temperature
- At equilibrium the amount of reactants and products stay the same. As the reactants get used up, the forward reaction slows down_and as more products are formed the reverse reaction speeds up.
