For the process

   CaCO3(calcite) → CaCO3(aragonite)   ΔH° = -0.21 kJ, ΔS° = -4.2 J/K

Assuming that the surroundings can be considered a large heat reservoir at 25°C, calculate ΔSsurr and ΔStotal for the process at 25°C and 1 atm pressure. Is the process spontaneous at 25°C and 1 atm pressure?
A) ΔSsurr = 4.2 J/K, Δtotal = 0, not spontaneous
B) ΔSsurr = 0.7 J/K, ΔStotal = -3.5 J/K, not spontaneous
C) ΔSsurr = -0.7 J/K, ΔStotal = -4.9 J/K, spontaneous
D) ΔSsurr = -0.7 J/K, ΔStotal = -4.9 J/K, not spontaneous
