Chapter 6, Problem 45IP

Interpretation Introduction

Interpretation:

The impact of temperature on product formation should be predicted and justified.

Concept introduction:

Sigma bond: A molecular orbital forms end-to-end overlap of atomic orbitals which forms covalent bond is called sigma bond.

Pi bond: A molecular orbital forms end-to-end overlap of atomic orbitals which forms a covalent bond is called π bond.

General formula to calculate the Gibbs free energy is $\text{ΔG = ΔΗ –TΔS}$

$\text{ΔΗ}$ = Enthalpy, ΔH is determined by the system not by the surrounding, a system that releases heat to the surrounding and it is called exothermic reaction and $\text{ΔΗ}$ is negative.

$\text{ΔS}$ = Entropy, a measure of the randomness of the system.

$\text{ΔS}$ (Entropy) of the molecule should be identified by using further down formula.

$\text{ΔS}$ = Number of products – Number of reactants
