Get PriceΔ G m = 0. Click here for the answer. ANSWER. B. Δ G m < 0. If Δ H m = 0 and Δ S m > 0, then by using Δ G = Δ H − T ⋅ Δ S , we know Δ G must be negative and mixing for an ideal solution will always be spontaneous. So we know that entropy increases in an ideal solution and this is what drives the spontaneous mixing.
