For the acids, use the formula pH =-log[H*]. (Because HCI has 1 H* ion per formula unit, [H*] equals the molarity.) For water, use what you know about the pH of neutral solutions. For the bases, examine and
extend the pattern.

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 :
