Given the following data:
2O3 > 3O2 (enthalpy = 427 kJ)
O2 > 2O (enthalpy = +495 kJ)
NO + O3 > NO2 + O2 (enthalpy = 199 kJ)
Calculate the enthalpy for the reaction
NO + O > NO2 using Hess's Law.

Best ResponseYou've already chosen the best response.1Just try to find how you will gt the reaction by adding the other reactions. reverse the second eq as O is in reactant side and half it.. Now in the final reaction there is neither ozone nor oxygen so now you have oxygen in the products side after adding reversed 2 and 3, O >1/2 O2 adding this to the third eq you get, NO+O +O3 > NO2 +3/2 O2 Now you need to remove O3 and O2 using the first equation, So reverse the first one,half it and add, 3/2O2> O3 adding it removes O3 and O2 you get the requires equation, NO + O>NO2 you can do the calculation bit yourself when you add reactions Enthalpy is also adde by hess law so yeah that part shld be pretty simple.
