Question:
European regulations state that all new cars have to be fitted with catalytic converters as part of their exhaust system.
a. Why are these regulations necessary?
b. Which gases are removed by catalytic converters?
c. Which metals are often used as catalysts in catalytic converters?
d. What does the term ‘poisoned’ mean with respect to catalysts?
e. The latest converters will also remove unburnt petrol. An equation for this type of reaction is:
2C7H14(g) + 21O2(g) →14CO2(g) + 14H2O(g)
(i) Calculate the mass of carbon dioxide produced by 1.96 g of unburnt fuel.
(ii) Convert this mass of carbon dioxide into a volume measured at rtp.
(iii) If the average car produces 7.84 g of unburnt fuel a day, calculate the volume of carbon dioxide produced by the catalytic converter measured at rtp. (Ar: H = 1; C = 12; O = 16. One mole of any gas occupies 24 dm3 at rtp.)
Step by Step Answer:
a These regulations are necessary because car exhausts produce harmful gases such as carbon monoxide ...View the full answer
