4. Which of the following NOT TRUE about real gas 1. The molecules actually do occupy some space
II. Intermolecular force are negligible
III. No repulsion between molecules when molecules
become closer
IV. When the distance between molecules decrease,
the attraction or repulsion become greater
O A. II & III
O B.
C. IV
O D. 11 & IV

The answer is D.

Explanation:

Intermolecular force are negligible

When the distance between molecules decrease,

the attraction or repulsion become greater

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 :
