4.) An inner-tube is inflated to 3.45 x 104 mL on a cold winters day at -20.0 oC. This same innertube is later stored in a garage where the temperature reaches 26.7 oC. What is the
new volume of the inner-tube?

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 :

12 is it do you think so
