Ethanol $($grain alcohol$)$ is a renewable energy additive that can be made from glucose obtained from the fermentation of grain. Determine the standard enthalpy of reaction for

$C_6{H}_{12}{O}_6(s)2C_2{H}_{5}OH(l)+2C{O}_2(g),{}_{r}H=?$

from the following reaction equations.

$C_6{H}_{12}{O}_6(s)+6O_2(g)6C{O}_2(g)+6H_{2}O(l)+2803\mathrm{.}1kJ$

$C_2{H}_{5}OH(l)+3O_2(g)2C{O}_2(g)+3H_{2}O(l)+1366\mathrm{.}8kJ$
