level questions: Reversible reactions
| Question | Answer |
|---|---|
| What does reversible reaction mean | The products can be combined to make the reactants vice versa |
| Exothermic and Endothermic | If the forward reaction is exothermic the backwards reaction will be endothermic |
| How is energy conserved in a chemical reaction | The energy released/ absorbed by the forward is the same as the energy released/ absorbed by the backwards |
| What is a closed system | Reactants and products can either be added nor removed |
| What happens if a reversible reaction happens in a closed system | A dynamic equilibrium would be reached |
| What happens at dynamic equilibrium | - The rate of the forwards is the same as the rate of backwards - Its dynamic because both forward and backward reactions are still taking place |
| What happens when we change the conditions in a reversible reaction | The position of equilibrium is changed |
| What was Le Chatelier's principle | If any of the conditions in a reversible reaction are changed the system will change to counteract this change |
