a. Define standard enthalpy change of reaction. b. Given the enthalpy changes H 1 and H 2
Question:
a. Define standard enthalpy change of reaction.
b. Given the enthalpy changes ΔH1 and ΔH2 below, construct a Hess’s cycle that will enable you to find the enthalpy change, ΔHr, for the reaction:
MgCO3(s) MgO(s) + CO2(g) ΔHr
MgCO3(s) + 2HCl(aq) MgCl2(aq) + CO2(g) + H2O(l) ΔH1
MgO(s) + 2HCl(aq) H2O(l) + MgCl2(aq) ΔH2
