Interpretation Introduction

Interpretation:

For the given reaction effect of ${\text{K}}_{\text{eq}}$, $\text{ΔG}$ (Gibbs free energy), temperature, $\text{ΔΗ}$ (Enthalpy), ${\text{E}}_{\text{a}}$ and $\text{ΔS}$ (Entropy) should be identified.

Concept introduction:

Equilibrium constants ( ${\text{K}}_{\text{eq}}$) $\text{= }\frac{\left[\text{Products}\right]}{\left[\text{Reactants}\right]}$

Equilibrium constants ( ${\text{K}}_{\text{eq}}$) is only affected by temperature, because if number of moles of the reagent increases product will also increases and the ratio constant.

$\text{ΔΗ}$ (Enthalpy) could be determined by using following formula

$\text{ΔΗ}$ (Enthalpy of the reaction) = $\text{ΔΗ }\left(\text{bonds broken}\right)\text{ – ΔΗ (bonds formed)}$

$\text{ΔS}$ (Entropy) can be identified by using formula.

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

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