The solubility of manganese(II) fluoride in water is 6.6 g/mL at 40°C and 4.8 g/L at 100°C.Based on these data,what is the sign of ΔH° and ΔS° for the process below? MnF2(s) ⇌ Mn2+(aq) + 2 F-(aq)
A) ΔH° is negative but the sign of ΔS° cannot be determined from this information.
B) ΔH° is negative and ΔS° is definitely negative.
C) ΔH° is positive but the sign of ΔS° cannot be determined from this information.
D) ΔH° is positive and ΔS° is definitely negative.
