level questions: Reversible reactions
| Question | Answer |
|---|---|
| What are reversible reactions? | Reactions which the products can form the original reactants The arrow in the formula has 2 heads ⇌ e.g. A+B ⇌ C+D |
| What happens if the forward reaction is exothermic? | The backward reaction is endothermic |
| Hydrated definition? | surrounded by water |
| Dynamic equilibrium definition? | The forward and backward reaction are happening at the same rate. Concentration of all the reacting substances remain constant |
| How can the equilibrium be changed? | 1)Increase in pressure-equilibrium moves to direction of fewest molecules of gas to reduce pressure 2)Increase in concentration-equilibrium moves away from reactant 3)Increase in temperature- equilibrium moves to endothermic reaction to reduce temperature |
