## The value of ∆G° for the reaction 2 C 4 H 10 ( g ) + 13 O 2 ( g )   → 8 CO 2 ( g ) + 10 H 2 O ( l ) is −5490. kJ. Use this value and data from Appendix 4 to calculate the standard free energy of formation for C4H 10(g).

Interpretation Introduction

Interpretation: The standard free energy change of formation of C4H10 gas in the given reaction using data from appendix 4 is to be calculated.

Concept Introduction: The standard free energy change of the reaction is difference of sum of the standard free energy change of formation of products and reactants.

To determine: The standard free energy change of formation of C4H10 gas in the given reaction.

### Explanation of Solution

Given

The balanced chemical equation for the given reaction is,

2C4H10(g)+13O2(g)8CO2(g)+10H2O(l)

The standard free energy change of the reaction is 5490kJ .

The standard free energy change of the given reaction is calculated by the formula,

ΔG=nΔG(products)mΔG(reactants)=(8ΔGfCO2(g)10ΔGfH2O(l))(2ΔGfC4
