- reaction enthalpy Responsibility Reaction tropics (thermo-11)Think about it To you for all of them The the following Operations, whether or not in each case One Increase or One Decrease The entropy and The enthalpy of the Chemical products Systems to Expected is (z.B. ΔHoR Gt0 and so on.):
- CO2(s) Sublimated to CO2(g)
- Heating of CaCO3(s)
- CO2(g) + CaO(s) → CaCO3(s)
- H2O(s) → H2O(l) → H2O(g) → 0.5·O2(g) + H2(g)
- Ba(OH)2(s) + 2·NH4SCN(s) → Ba(SCN)2 + 2·NH3(g) + 2·H2O(l)
- NH3(g) + HCl(g) → NH4Cl(s)
