Given the values of ΔGfo given below in kJ/mol, calculate the value of ΔGo in kJ for the combustion of 1 mole of butane to form

xz_007 [3.2K]

Answer:

Δ $_rG=-2753kJ$

Explanation:

Hello,

Butane's combustion is:

$C_4H_{10}+\frac{13}{2} O_2-->4CO_2+5H_2O$

Now the change in the Gibbs free energy for this reaction is computed via (don't forget that oxygen's Gibbs free energy of formation is 0 since it is an element):

Δ $_rG=$ 4Δ $_fG_{CO_2}+$ 5Δ $_fG_{H_2O}$ -Δ $_fG_{C_4H_{10}}$

Δ $_rG=4(-395kJ/mol)+5(-238kJ/mol)-(-17kJ/mol)$

Δ $_rG=-2753kJ/mol$

Now, since the calculation is done for 1 mol of butane, the change in the Gibbs free energy for this fuel is:

Δ $_rG=-2753kJ$

Best regards.
