Reactive Material Balance: ConcepTest and Example Problem

Try to answer this ConcepTest and solve the example problem before using this module. Studies show that trying to answer the questions before studying material improves learning and retention. We suggest that you write down the reasons for your answers. By the end of this module, you should be able to answer these on your own. Answers will be given at the end of this module.

Example Problem 1

100 moles of ethane are sent to a reactor and react to form ethylene and hydrogen gas. However, some of the ethylene reacts with the ethane to form propylene and methane. If the fractional conversion of ethane is 0.70 and the selectivity of ethylene to propylene is 5, find the composition of the product gas using atomic species balances.
