The gases listed are at standard temperature and pressure
• 1 mol of Co, gas
• 1 mol of N, gas
• 2 mol of O, gas
Which statement is correct?
The volume of 1 mol of Co, is greater than that of more
The volume of 1 mol of Co, is greater than that of moto
The volumes of 2 mol of O, and 1 moto goes are the same
The volumes of 1 mol of Co, and 1 mol of Ne gases are the same

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 :

the answer is d. matter from the air combined with the steel wool.
