We always need to have at least one flow rate specified. In other words,
we need a basis. So if we assume a basis in one of the streams in the
overall process, we can go from one degree of freemdom down to zero
and start solving for the unknowns

100 moles of ethane are sent to a reactor and react to form ethylene and hydrogen gas.
However some of the ethylene reacts with ethane to form propylene and methane. If the
fractional conversion of ethane is 0.70, and the select

The term standard cubic meters (or SCM) is often used to denote m3 (STP), and standard c1
feet (or SCF) denotes ft3 (STP). A volumetric ow rate of 18.2 SCMH means 18.2 m3/h at l
