The atoms and molecules in a gas are in constant motion. temperature is a measure of this motion. how are these related?

a. as temperature increases, the molecules and atoms move faster. as temperature b. decreases, the molecules and atoms move farther apart.
c. as temperature increases, the atoms and molecules move farther apart.
d. as temperature decreases, the molecules and atoms move faster.

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 :
