Chapter 14, Problem 14.38QP

Interpretation Introduction

Interpretation:

The explained about calculation methods for concentration of reaction species (Kc) given the equilibrium reactions.

Concept Introduction:

The Law of Mass Action: The rate of chemical reaction is directly proportional to the products of activates and different concentration of the reactants. Further this process explained the behaviors of solution in dynamic chemically equilibrium.

Basic concept of chemical equilibrium: The chemical equilibrium happen in phase transition process, consider for some example, if the temperature in a one system containing a mixture of ice and water is uniformly temperature 273.15 K, the net amount of ice formed and the melt will be zero. The amount of liquid water will also remain constant, if no vapor escape from the system. In this case, three phases, ice (solid) water (liquid), and (gas) are in equilibrium with one another. Equilibrium conditions also exist between solid phase and vapor phases. These are phase equilibria.

Reaction quotient: This type of chemical equilibrium reaction proceeds likely to produced, given either the pressure (or) the concentration of the reactants and the products. The value can be compared to the equilibrium constant, to determine the direction of the reaction that is take place. Then reaction quotient (Qc) the indication of Q can be used to determine which direction will shift to reach of chemical equilibrium process.

To find: The equilibrium concentration (Kc) reaction outline should explain given the statement.
