- What is the implication of the following reaction arrows?
- →
The reaction runs to completion.
The reaction reaches equilibrium.
- In general, reactions go to equilibrium.
- What is equilibrium?
Equilibrium is the point in a reaction where the rate of the forward reaction equals the rate of the reverse reaction.
- Why does equilibrium occur?
Initially there is only reactant in the reaction vessel – therefore the reaction can only proceed in the forward direction. After some time the concentration of the products increases to an amount that ups the probability that product will be able to find each other and reactant in the reverse direction. A point is achieved at which the formation of reactant equals the formation of product – this is equilibrium.
- It is important to remember that equilibrium is
- Macroscopically static.
- Microscopically dynamic.
- How is the equilibrium point described?
The numerical value of K describes the equilibrium point.
