Select all the true statements regarding chemical equilibrium:
- The concentrations of reactants and products remain constant.
- The concentrations of reactants and products are equal.
- Reactants are still being converted to products (and vice versa).
- The rates of the forward and reverse reactions are equal.
Answer
The first statement is false because the products and reactants can have different concentrations.
The second statement is true, because when neither the products nor the reactants have a change in concentration, then the equilibrium is established.
The third statement is also true because reactants are still being converted to products in a constant manner (such that it appears like nothing is happening).
The fourth statement is also true because it is a property of chemical equilibrium.
The tree statements are:
- The concentrations of reactants and products are equal.
- Reactants are still being converted to products (and vice versa).
- The rates of the forward and reverse reactions are equal.
