Chapter 5, Problem 12E

(a)

Interpretation Introduction

Interpretation:

The acid-base reaction between the following pairs of reactant should be written by using curved arrows and each curved arrows should be marked with a positive and negative energy change in $p{K}_a$ units.

  

  

  

  

Concept Introduction:

A substance which produces ${\text{H}}^{+}$ or proton when dissolved in aqueous solution is known as an acid. These are proton donor.

A substance which produces hydroxide ion when dissolved in aqueous solution is known as a base. These are proton acceptor.

A chemical reaction which takes place between an acid and a base is known as acid-base reaction.

The value that defines the relationship between the amount of products and reactants at equilibrium is known as equilibrium constant.

(b)

Interpretation Introduction

Interpretation:

The value of $\text{ΔH}$ for each reaction should be calculated and the energy diagram should be drawn.
