level questions: Factors that affect equilibrium
| Question | Answer |
|---|---|
| What is the effect of temperature change on chemical systems at equilibrium? | Considering the enthalpy change for the forward and reverse reactions; an endothermic forward reaction will shift to the right with increasing temperature, while an exothermic forward reaction will shift to the left. |
| Define Le Châtelier’s principle. | If a system in equilibrium is subjected to a change in temperature, pressure, or concentration, the system will adjust to counteract the change and restore equilibrium. |
| What is the effect of changing concentration and pressure on chemical systems at equilibrium (applying collision theory). | Shifts the chemical equilibrium of a reaction by affecting the rate of forward and reverse reactions based on collision theory; increasing concentration or pressure favors side with less moles of gas, while decreasing concentration or pressure shifts the equilibrium in the direction to oppose the change. |
