Which is true of the products in this combustion reaction? 4fe + 3o2 2fe2o3

a. the products contain 4 iron atoms and 6 oxygen atoms.

b. the products are located to the left of the arrow in the chemical equation.
c. the products have the same physical and chemical properties as the reactants.
d. the products are the atoms, molecules, or compounds that participate in the reaction.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
