Multiple Choice

Which is not true?

• Chemical reactions that can change direction are called reversible reactions.

• A reversible reaction can be at equilibrium when no net change occurs in the amount of reactants and products.

• Le Chatelier’s principles says that if a system is at equilibrium has stress applied to it will shift in the direction that relieves the stress.

• Such a system in which opposite reactions are taking place at the same rate is said to be at infrequent disequilibrium.
