Text Solution

AI Generated Solution

To find the Gibbs free energy change (ΔG) for the reaction: \[ S_{(rhomb)} + O_2(g) \rightarrow SO_2(g) \] we will use the given reactions and their respective ΔG values. We can apply Hess's Law, which states that the total enthalpy change for a reaction is the sum of the enthalpy changes for the individual steps. ### Step-by-step Solution: ...
