(a) Calculate the enthalpy effect H for dissolving 1 mol of solid nickel in 9 mol of liquid copper at 1473 K, assuming an ideal solution is formed. In other words, the enthalpy o f mixing liquid (Cu,NI) alloys is negligibly small and can be taken to be zero. The enthal pies of melting for NÍ and Cu are 17,470J mol-1 at Trus = 1726 K and 13,055 J molř at Tf us = 1356.6 K. (b) Calculate the entropy change of the system and of the surroundings for this proces S.
