The given reaction is between solid iron and aqueous copper (II) bromide to form solid copper and aqueous iron (II) bromide. Iron being more reactive than copper can displace copper ion from its aqueous solution. Therefore, this reaction is an example of single replacement reaction in which Iron displaces copper from an aqueous solution of copper (II) bromide.

Word equation :

Iron (solid)+Copper(II) bromide(aqueous)--->Copper (solid)+Iron (II) bromide (aqueous)

Chemical equation:

Fe(s) +CuBr_{2}(aq)-->Cu(s)+FeBr_{2}(aq)

ΔG⁰ = ΔH⁰ - TΔS
ΔH⁰ = Hf,(CH₃OH) - Hf,(CO) = -238.7 + 110.5 = -128.2 kJ/mol
ΔS = S(CH₃OH) - S(CO) - 2S(H₂) = 126.8 - 197.7 - 2 x 130.6 = -332.1 J/mol.K
So 
ΔG⁰ = - 128200 + 332.1 T
For the reaction to be spontaneous:
ΔG⁰ < 0
So: -128200 + 332.1 T < 0
332.1 T < 128200
T < 386.028 K
