Answer 1

Answer #1

Using the thermodynamic data of energy:

∆G = (Gibbs energy of product) - ( Gibbs energy of reactants)

Reaction given is

H2 + 1/2(O2) >>> H2O

Considering H2O in liquid state, as not given

∆G (H2O) = -237.13 KJ/mol

Gibbs energy for hydrogen and oxygen are taken as zero as per convention

So change in free energy for above reaction is = -237.13 KJ/mol
