Answer:

2C(s, graphite)+ 3H₂(g) + ½O₂(g) ⟶ C₂H₅OH(ℓ)  

Explanation:

The thermodynamic standard state of elements and compounds is defined as their most stable state at 25 °C and 1 bar

The elements in ethanol, C₂H₅OH, are C, H, and O.

Their most stable states at standard conditions are C₂H₅OH(ℓ), C(s, graphite), H₂(g), and O₂(g)

The equation for the formation of ethanol from its elements is  then

2C(s, graphite) + 3H₂(g) + ½O₂(g) ⟶ C₂H₅OH(ℓ)
