What can be said about a reaction with H=-890 kJ/mol and AS= -0.24 kJ/(mol-K)? A. it is never spontaneous B. it is always spontaneous C. it is spontaneous at 2000 k D. it is at equilibrium at 371 k

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
