According to the kinetic molecular theory, which of these statements is not true? a. there is no attraction between particles of a gas. b. only particles of matter in the gaseous state are in constant motion. c. the particles of a gas collide with each other and with other objects. d. most of the volume of a gas is just empty space.

B; false, all forms are slightly moving or vibrating, even solids

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 :
