Assume the cell potential from part a is the same as the standard cell potential for your ascorbic acid cell. What would the cell potential be if the copper electrode was replaced with the standard hydrogen electrode for the pH 5 cell? Hint: Think about which was the reference (anode).

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 :
