1. compounds a and b enter a mixer in stream 1, where they are mixed with a recycle stream (stream 5). the streams combine and exit the mixer as stream 2, which is then fed to a reactor. the reactor has the reaction 3a + b2c, and 80 % conversion (molar) of a. the unreacted a and b, as well as any c produced, exit the reactor in stream 3, which is then fed to a separator. the separator removes all of compound c produced in the reactor as stream 4, which is pure c and has a flowrate of 500 mol/hr. the remaining a and b are recycled back to the mixer as stream 5. give all flowrates in mol/hr a draw the process flow diagram. label the diagram and circle unknowns. b. determine how much c exits the reactor c. how much a and b are consumed in the reactor? d. how much a enters the reactor? e. if b is provided in 50% excess, how much b enters the reactor? f determine the total flowrates in and out of the reactor. g. find the total flowrate and composition of the recycle stream. h. determine the composition and flowrate of the fresh feed (stream 1)
