Calculate the standard enthalpy change for the reaction of [Co(H2O)6]2+(aq) with 2 Cl-(aq) to form [CoCl4]2-(aq) and 6 H2O(l) at a temperature of 298 K. Given the following thermodynamic data:[Co(H2O)6]2+(aq) + 4 Cl-(aq) → [CoCl4]2-(aq) + 6 H2O(l) ΔH°= -98.7 kJ mol-1[Co(H2O)6]2+(aq) + 2 Cl-(aq) → [CoCl4]2-(aq) + 4 H2O(l) ΔH°= -65.5 kJ mol-1Assume that the enthalpy of hydration for Cl- (aq) is -364 kJ mol-1.
