reversible reactions Flashcards
What is a reversible reaction?
A reaction where products can be changed back into reactants
What is a dynamic equilibrium?
Where the forward and backward reactions in a reversible reaction are happening at the same rate
What is needed to achieve equilibrium?
The reaction needs to happen in a closed system- where no reactants or products can escape
Which compound is produced using the haber process?
ammonia
What are the reactants in the haber process?
nitrogen gas and hydrogen gas
Which temperature is the haber process carried out at?
450oC
Which pressure is used for the haber process?
200 atmos
Which metal is used as a catalyst for the haber process?
iron
What can alter the position of an equilibrium?
changing pressure, changing concentration and changing temperature
What happens to the position of the equilibrium if pressure is increased?
if pressure increases, the equilibrium position moves in the direction of the fewest gas molecules
What happens to the position of equilibrium if concentration of a reactant increases?
The equilibrium will move to favour the product
What will happen to the position of equilibrium if temperature is increased?
The equilibrium moves to favour the direction which is endothermic
