Read the chemical equation. Fe2O3 + CO → Fe + CO2

If 3 moles of Fe2O3 react with 1.5 moles of CO, how many moles of each product are formed? (3 points)

1 mole of Fe and 1.5 moles of CO2

0.5 mole of Fe and 1 mole of CO2

6 moles of Fe and 9 moles of CO2

3 moles of Fe and 2 moles of CO2

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 :
