b. heat of fusion
c. charles’s law
d. the kinetic theory of matter

The kinetic theory of matter

Explanation:

The kinetic theory of matter states that the atoms of every matter are in continuous constant motion. forms of matter can be grouped solid, liquid or gas. The molecules of a solid vibrate about their mean position. The molecules of liquid vibrate and can flow and they also take the shape of their container. The molecules of a gas  are in constant random motion and collide with each other and with the walls of their containing vessel.

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 :
