For you last required journal entry of the quarter, but on a separate piece of paper, create a poster which compares the mass of a mole of candy to something interesting. for example, “the mass of a mole of m& m’s is equal to the mass of 1,000 jupiters” (this may not be true, i made it up.) show the math neatly in one corner of the poster.

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 :
