How will the freezing point and boiling point of a liquid be affected if you add a solute such as sugar or salt to it? What will happen and why? Compare the effects of adding 5 ml, 25 ml, and 50 ml of solute.

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 :

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
