Will the reaction,
`I_(2)(s) +H_(2)S(g) rarr 2HI(g) +S(s)`
proceed spontaneously in the forward direction of `298K`
`Delta_(f)G^(Theta)HI(g) = 1.8 kJ mol^(-1), Delta_(f)G^(Theta)H_(2)S(g) = 33.8 kJ mol^(-1)`?

To determine if the reaction \[ I_2(s) + H_2S(g) \rightarrow 2HI(g) + S(s) \] will proceed spontaneously at 298 K, we need to calculate the standard Gibbs free energy change (\( \Delta G^\circ \)) for the reaction. A reaction is spontaneous in the forward direction if \( \Delta G^\circ < 0 \). ### Step-by-Step Solution: ...
