Alcohols for use as biofuels can be produced from glucose that is obtained from starch and cellulose in plants. For example, 1 mol of glucose can produce 2 mol of ethanol. Use the information in the table below to determine the maximum amount of work and energy that can be produced by the combustion of glucose compared with that by the combustion of 2 mol of ethanol.
C₆H₁₂O₆(s)

\longrightarrow

2CH₃CH₂OH(l) + 2CO₂(g)

\begin{array} { | c | c | } \hline \text { Compound } & \\& \Delta G _ { \mathrm { f } } ^ { \circ } \\& ( \mathbf { k J } / \mathbf { m o l } ) \\\hline \text { Glucose } ( s ) & - 910 \\\hline \text { Ethanol } ( l ) & - 175 \\\hline \text { Water } ( g ) & - 229 \\\hline \text { Carbon dioxide } ( g ) & - 394 \\\hline\end{array}

A) 1 mol glucose = 2,830 kJ, 2 mol ethanol = 2,600 kJ
B) 1 mol glucose = 2,830 kJ, 2 mol ethanol = 1,300 kJ
C) 1 mol glucose = 2,190 kJ, 2 mol ethanol = 2,780 kJ
D) 1 mol glucose = 1,420 kJ, 2 mol ethanol = 1,390 kJ
E) 1 mol glucose = 2,190 kJ, 2 mol ethanol = 1,300 kJ
