What is the temperature of a gas in which the atoms are moving very, very slowly?

Their temperature is low

Explanation:

For gas atom moving slowly, their kinetic energy would be quite low. Low kinetic energy would result into lesser number of colliding particles and low heat being generated. Therefore, the temperature would be very low.

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 :
