Carbon monoxide is often used in metallurgy to remove oxygen from metal oxides and thereby give the free metal. The thermochemical equation for the reaction of CO2 with Fe2O3 is Fe2O3 (s) + 3 CO (g) ------------> 2 Fe (s) + 3 CO2 (g) delta H rxn ^0 = ? Give that delta H (subscript f) ^0 Fe2O3 (s) = -824.2 kJ/mol, delta H (subscript f)^0 CO (g) = -110.5 kJ/mol and delta H (subscript f)^0 CO2 (g) = -393.5 kJ/mol, determine the enthalpy change, delta H rxn^0 for the reaction given above. And please show me the steps
At what temperature will nitrogen gas (N2) have the same density as helium gas (He) at 27 degrees C and constant pressure
The rate constant for electron transfer between V 2+ (aq) and V 3+ (aq) is observed to depend on [H+]: k = a + b/[H+], where a and b are constants. Propose a mechanism and express a and b in terms of the rate constants in your mechanism.
