Question

For the reaction shown below, G°rxn is 142 kJ. In which direction is the reaction spontaneous at 25°C, when the pressures of SO2, O2, and SO3 are 0.1 atm, 0.2 atm, and 1 × 10-4 atm, respectively.

2 SO2(g) + O2(g) 2 SO3(g)

The reverse reaction is spontaneous under these conditions.

The forward reaction is spontaneous under these conditions.

Neither the forward nor reverse reactions are spontaneous; it is at equilibrium under these conditions.

There is not enough information to determine whether the forward or reverse reaction is spontaneous under these conditions.

Explanation / Answer

Sulphur and oxygen react to gether to form so2 and it is a oxidation reaction.oxidation of the sulphur is a exothermic reaction

sulphurdioxide is oxidized sulphurtrioxide.catalyst is vanadium oxide this reaction is reversible reaction
