An empty fuel tank can still contain and therefore can be even more dangerous than one full of liquid fuel.

An empty fuel tank can still contain "fumes"

Explanation:

Even if there is not enough liquid fuel, whatever is left in the tank creates fumes, which is more combustible than liquid gas.

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 :
