Which of the following statements is true regarding hydrogen bonds? Hydrogen bonds are weaker than covalent and ionic bonds.

Hydrogen bonds are weaker than ionic bonds but not covalent bonds.

Hydrogen bonds are stronger than covalent and ionic bonds.

Hydrogen bonds are weaker than covalent but not ionic bonds.

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 :
