If two elements have the same value of the quantum number n and different l, ml and ms then they must be in: *The same orbital, but different level and sub level.
*Different level, sublevel and orbital
*The same level, sub level and orbital.
*The same level, but different sublevel and orbital
*The same sub-level and orbital but different level.

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 :
