Question

Part A

A reaction that has reached equilibrium has which of the following properties?

Check all that apply.

1.The rate of the forward reaction is greater than the rate of the reverse reaction.

2.The rate of the forward reaction is equal to zero.

3.The amount of the products is greater than the amount of reactants.

4.The amounts of products and reactants stay the same once equilibrium is reached.

Part B

What is the pH of an aqueous solution with [H3O+] = 4×1013 M ? Express the pH numerically using one decimal place.

Part C

Identify acid, base, conjugate acid, conjugate base, and the relative strengths of the species involved in the reactions.

HCl + NH3 -> NH4+ + Cl-

Name Species and Strength for each product and reactant.

Explanation / Answer

Part A :     4.The amounts of products and reactants stay the same once equilibrium is reached.

Part B:     12.4

Explanation: pH = -log[H+] = -log[H3O+] = -log[4×1013] = 12.4

Part C:

HCl --> acid (strong)

NH3 --> base (weak)

NH4+ --> conjugate acid (weak)

Cl- --> conjugate base (weak)
