Reversible Reactions Flashcards
What is a reversible reaction?
A reversible reaction is one where the products of the reaction can react with themselves to produce the original reactants.
What will happen if the reaction is kept in a closed system?
A state of equilibrium will be reached, which means that the amounts reactants and products will reach a certain balance and stay there, both the reactions are happening at the same rate and the same time so they cancel each other out.
What happens is you raise or lower the temperature?
If you raise the temperature, the endothermic reaction will use up the extra heat. If you lower the temperature, the exothermic reaction will increase to give out more heat.
What happens if you change the pressure?
If you raise the pressure it will encourage the reaction which produces less volume. If you reduce the pressure it will encourage the reaction which produces more volume, as the two sides of the reaction don’t have the same amount of products / reactants.
What does a catalyst do?
It doesn’t change the equilibrium position, just speeds up the time that it takes to get to an equilibrium.
