Based on the general trends on intermolecular forces, rank c2h5oh, hcl, and c3h6 in order of increasing boiling point.

The increasing order of boiling point is HCl, C3H6, C2H5OH.

Explanation:

The increasing order of boiling point is:

HCl = -85°C

C3H6 = -47.6°C

C2H5OH = 78.5°C

The boiling point is directly proportional to the strength of inter-molecular forces.

HCl molecule has weak, dipole-dipole and Van der waal's forces, thus it has smallest boiling point.

C3H6 has the second less boiling point owing to the presence of one double bond.

C2H5OH has the highest boiling point due to strong hydrogen bonding.

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 :
