Part D Scientists have done careful and repeated experiments to determine enthalpy changes for many different chemical reactions. The accepted reaction enthalpies for the chemical reactions in tasks 1 through 3 are given in the table. Compare your experimentally determined reaction enthalpies from these tasks with the accepted enthalpies. Are your results similar to or different from the accepted values? What may have contributed to any differences? Reaction Accepted Reaction Enthalpy, AH CuSO4 + 5H20 = CuSO4.5H2O -78,000 J/mol Zn + CuSO4 = Cu + ZnSO4 -217,000 J/mol H3C6H507 + 3NaHCO3 = Na3C6H507 + 3C02 480,000 J/mol + 3H20​

According to le chatelier’s principle, a system in chemical equilibrium responds to stress by shifting the equilibrium in a direction that reduces the stress. normalizes the stress. increases the stress. changes the stress.
