For the reaction shown below, G rxn is 142 kJ. In which direction is the reaction spontaneous at 25C, when the pressures of SO2,

For the reaction shown below, Δ 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.
