Competition Wallah・2 minutes read
Equilibrium in chemical and ionic forms involves reversible reactions and understanding reaction rates to achieve balance. Factors like temperature, concentration changes, and catalysts influence equilibrium, with pressure shifts impacting gaseous moles and the final outcome of reactions.
Insights
- Equilibrium involves balancing forward and backward reactions, with rates being equal.
- Catalysts impact equilibrium by either speeding up or delaying reactions.
- Temperature influences equilibrium, affecting the direction of reactions.
- Pressure changes affect equilibrium position, with higher pressure favoring the side with fewer gaseous moles.

Recent questions
What is chemical equilibrium?
Chemical equilibrium occurs when the rates of forward and backward reactions are equal, leading to a constant state. It is dynamic in nature, with reactions proceeding in both directions at the same rate. At equilibrium, observables like pressure, volume, temperature, and concentration remain constant.
How do catalysts affect equilibrium?
Catalysts can affect equilibrium by speeding up reactions, with positive catalysts accelerating equilibrium and negative catalysts delaying it. Negative catalysts increase activation energy, while positive catalysts decrease it, impacting the time it takes for equilibrium to be reached.
What is the impact of temperature on equilibrium?
Temperature influences equilibrium; lower temperatures favor the backward reaction, while higher temperatures favor the forward reaction. Understanding how temperature affects equilibrium is crucial for predicting the direction in which a reaction will proceed.
How does pressure affect equilibrium?
Pressure affects the equilibrium position in a reaction; increasing pressure shifts the equilibrium towards the side with fewer gaseous moles. To maximize product yield, keeping pressure low is recommended to push the equilibrium towards the forward direction.
What is the significance of volume changes in equilibrium?
Equilibrium remains unaffected by changes in volume or the addition of inert gases at constant volume or pressure. Understanding how volume changes impact equilibrium is essential for predicting the behavior of a system under different conditions.
