Based on the kinetic molecular theory, which of the following statements is correct about the particles in a sample of gas? they have negligible kinetic energy. there is negligible force of attraction between them. the space between them decreases with increase in temperature. their average kinetic energy decreases with increase in temperature.

The correct answer is that there is negligible force of attraction between them. This is because the gas molecules are long distances apart distances that increase with increase in temperature.  The inter molecular force of attraction also decreases with the increase in temperature.

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 :
