Suppose that you made the experimental errors described below. Would these errors lead you to obtain a higher or lower molar mass of carbon dioxide? Explain your reasoning. A. Some CO2 gas leaked out of Flask B as you went to the balance room to weigh it.
B. When filling Flask B with water you did not fill it up to the brim, leaving some air at the top.

the answer would be c

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 :
