881
8.81 x 102
0.0881
88.1 x 10-2
8.81 x 10-3
88.1 x 101
88,100

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 :

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

that's what i got you can count the number of atoms
