In looking for a chemical to replace sodium azide in airbags, suppose that a cheap, nontoxic, and environmentally friendly chemical was found that decomposed more slowly, producing nitrogen over a period of several seconds. Would this chemical be a good replacement for sodium azide in airbags? Explain why or why not.

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 :

the maximum mass of nh3 is nh3 in grams
