- A vehicle airbag system works by using a series of chemical reactions. When sensors in the system detect a collision, a heat source instantly causes the decomposition of sodium azide at 300oC. This first reaction produces sodium metal and nitrogen gas. The formation of the nitrogen gas inflates the airbag, but unfortunately, the other product, sodium metal, is extremely dangerous and highly reactive. The sodium metal must undergo an immediate secondary reaction to transform into a safer substance. That’s where potassium nitrate gets involved. In the secondary reaction, sodium metal reacts with the potassium nitrate to form potassium oxide, sodium oxide, and additional nitrogen gas. This secondary generation of nitrogen gas also fills the airbag. Excess gas from the secondary reaction gets vented from e airbag. Finally, in the third and fourth reactions, the sodium oxide and potassium oxide react with silicon dioxide separately to product harmless and stable silicate glasses sodium…For the reaction2 NH3 (g) + CO2 (g) → CO(NH2)2 (s) + H2O (l)At 274.4 K, the following concentrations are observed:[NH3] = 0.814[CO2] = 0.843[CO(NH2)2] = 0.532[H2O] = 0.845a) What is the reaction quotient for this system?Find ∆H as a function of T for the reaction: CO2 (g) + C (s, graphite) = CO Given that ∆H 293= 41,400 cal Cp CO2= 5.166+15.77×10^-3 T - 95.78×10^-3 T² + 2.260×10^-9 T³ Cp CO= 6.6 + 2×10^-3 T Cp C (s, graphite)= 2.673 + 2.617×10^-3 T - 1.169×10^-5 T^-2
