La reaccin Zn(s) + CuSO 4 (aq) ZnSO 4 (aq) + Cu(s) se lleva a cabo con 25,0 ml de CuSO 4 0,50 M como reactivo limitante. Si la temperatura de la solucin aument 25,0 C y la masa de la solucin fue de 25,0 g, cul es el H de la reaccin, en kJ/mol? (suponga que el calor especfico de la solucin es 4,18 J/gC)
Recordar:
q solucin = masa x calor especfico x cambio de temperatura
-q solucin = q reaccin
H = q reaccin /moles de reactivo limitante
