Rate laws ethane thermal cracking

Thermal cracking of ethane is an excellent example of an intricate mechanism that leads to a kinetic behavior obeying a simple, first-order rate law in good approximation over a fairly wide range of conditions. It also serves to show how easily such a deceptively simple rate law is misinterpreted. Moreover, the example illustrates an important general point ...

Fig. 34.9 shows the results for hydrogen extraction from thermal cracking of ethane at 800 °C. Extraction rates were close to the theoretical calculated from Faraday s law, but a large part of the voltage required resulted from ohmic resistance of the proton conductor. If the ohmic resistance is excluded, however, the voltage required is fairly low as indicated with dotted lines in Fig. 34.9b. This means that, if a very thin and non-porous film of the proton conductor were available, it could be put to practical use as an electrochemical hydrogen separator.
