You are in a laboratory creating a new chocolate bar. you want to create the sweetest chocolate bar by maximizing the sugar concentration. you are doing this by adding the sugar to a chocolate mixture. which would allow you to dissolve more sugar? stir the sugar more vigorously. add the sugar after heating the mixture. add the sugar after cooling the mixture. decrease the particle size of the sugar.

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 :
