Studied by 1 personWhat is an irreversible reaction?
It is a reaction in which reactants are converted to products but the products can’t be changed back
e.g 2Mg + O2 → 2MgO
What is a reversible reaction?
It is a reaction in which the products can be changed back to reactants
e.g CuSO4 + 5H20 ⇌ CuSO4.5H2O
If a reversible reaction is exothermic in one direction what will it be in the other direction?
Endothermic
What is the criteria for a dynamic equilibrium?
-Occurs in a closed system
-Occurs when the rates of forward and reverse reactions are equal
-occurs when the amount of reactants and products remain constant
What is a closed system?
A system in which no substances can get in or out whereas an open system allows entry and exit of substances
What three species will be present in a closed system?
-The rate of forward reaction equals the rate of reverse reaction
-The amount of hydrogen and iodine remains constant
-The amount of hydrogen iodide remains constant
