Given the enthalpy changes of the following reactions:
2H2O2→2H2O+O2 ∆H=-200 kJ/mol
2H2O→2H2+O2 ∆H=+600 kJ/mol
What is the net enthalpy change for the following reaction?
2H2+2O2→2H2O2
2H2O2→2H2O+O2 ∆H=-200 kJ/mol
2H2O→2H2+O2 ∆H=+600 kJ/mol
What is the net enthalpy change for the following reaction?
2H2+2O2→2H2O2
- -200 kJ/mol
- -400 kJ/mol
- -600 kJ/mol
- -800 kJ/mole
