In a reaction between Iron and Oxygen, 0.043 mol of Iron is reacted with oxygen in the reaction below (equation is not balanced): __Fe+__O2->__Fe2O3

How many moles of Iron (III)oxide will be produced from this reaction? (Balance the equation first)

sry but any answer choices

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 :
