A new engineering graduate was putin charge of a reactor. The engineer quickly learned that the process called for the reaction of ethylene and hydrogen bromide to form ethyl bromide (C2H5Br). After combining the two reactants, the product stream was analyzed and found to contain 50 mol % C2H5Br, 20 mol % HBr and the remainder ethylene. The overall feed rate to the reactor was 165 mol/s (note: the feed to the reactor only contained ethylene and hydrogen bromide). The engineer must product a report. You must help them:a. Write the balanced equation.b. Draw a schematic of the process.c. Calculate how many moles of ethylene and hydrogen bromide are fed into the reactor.d.

Expert Answer

Step 1

Part (b)

The Schematic diagram of the given process is drawn below. The basis of the calculation is taken as 165 mol/s of the feed to the reactor. The process unit is the reactor in which the reaction takes place.

Step 2

Part (c)

The reaction between ethylene and hydrogen bromide is taking place in the reactor, so, apply material balance on individual elements.

Let the mole fraction of ethylene fed to the reactor be xF and the molar flowrate of the product stream be nP.

Apply Carbon (C) balance on the overall process and label it as equation (1) and apply material balance on Bromide (Br) and label it as equation (2) as:

Step 3

Solve equation (1) and (2) simultaneously to calculate the values...
