Consider a fuel cell that uses the reaction of ethanol with oxygen to produce electricity. ch 3 ch 2 oh ( l ) + 3 o 2 ( g ) ⟶ 2 co 2 ( g ) + 3 h 2 o ( l ) use thermodynamic data to determine the value of e ∘ cell for this cell at 25 °c .

The for the reaction is 1.14V.

Explanation:

The given chemical reaction is as follows.

The can be calculated by the following formula.

Rearrange the formula is as follows

n= Number of moles of electrons transferred.

Therefore, The for the reaction is 1.14V.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
