Sulphur exists is more than one solid form. The stable form at room temperature is rhombic sulphur. But above room temperature the following reaction occurs.
`S ("rhomic") rarrS("monoclinic")`
If `DeltaH^(Theta) =- 276.144J at 298 K` and `1atm` and `DeltaG^(Theta) = 75.312J`
a. Calculate `DeltaS^(Theta)` at `298K`.
b. Assume that `DeltaH^(Theta)` and `DeltaS^(Theta)` do not vary significantly with temperature, calculate `T_(eq)`, the temperature at which rhombic and monoclinic sulphur exist in equilibrium with each other.
