Chapter 18, Problem 18.21QP

Interpretation Introduction

Interpretation:

The equilibrium constant should be calculated for the following reactions at ${25}^{0}C$.

Concept Introduction

Spontaneous Reaction: A reaction is said to be spontaneous if it occurs without being driven by some outside force. There are two driving force for all Chemical reactions.

The first is enthalpy, and the second is entropy. In this reaction the outside intervention does not influenced the reaction.

Electrochemical cell potential: The cell potential for an electrochemical cell can be predicted from half-reaction and its operating condition.

Standard cell potential:

In an electrochemical cell, an electric potential is created between two dissimilar metals.

This potential is a measure of the energy per unit charge which is available from the oxidation /reduction reaction.

To Calculate The equilibrium constant is calculate at the given temperature ${25}^0\text{C}$ for the following reaction.
