How does adding salt affect the freezing point of water

When salt is added into the water, often times, and salt and chlorine ions would mix with water molecules. The ions they carry affect the temperature of  the body of water, however when the water is freezing the ions would have a hard time mixing thus, retaining the liquid form of the water but the temperature slowly goes down.

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 :
