What is the product formed in the reaction 2A + 3B <----> 2AB?

Back

AB

Front

What does the symbol <----> indicate about a chemical reaction?

Back

The reaction is reversible.

Front

In a concentration vs. time graph, what does label (a) represent if (a) is the concentration of reactants and (b) is the concentration of products?

Back

(a) is the concentration of reactants and (b) is the concentration of products.

Front

Which statement is NOT true at equilibrium?

Back

The concentration of the reactants is equal to the concentration of the products.

Front

Which experiments reach equilibrium?

Back

All except experiment 2.

Front

Define chemical equilibrium.

Back

A state in a reversible reaction where the rates of the forward and reverse reactions are equal.

Front

What happens to the concentrations of reactants and products at equilibrium?

Back

The concentrations remain constant.

Front

What is Le Chatelier's Principle?

Back

If a system at equilibrium is subjected to a change in concentration, temperature, or pressure, the system will adjust to counteract that change.

Front

What is the difference between a reversible and an irreversible reaction?

Back

A reversible reaction can proceed in both directions, while an irreversible reaction can only proceed in one direction.

Front

What does it mean if a reaction is at dynamic equilibrium?

Back

The forward and reverse reactions continue to occur, but the concentrations of reactants and products remain constant.
