3. (6 pts The reaction A+2B2C takes place in a membrane reactor. The feed is only A and B in equimolar proportions. Which of the following sets of equations gives the correct mole balances on A, B and C? Species A and B are disappearing and Species C is being formed - A and C is also diffusing out the sides of a membrane reactor. Circle the correct answer where all the mole balances are correct (-s-ko10.ci-) 12 (c) (a) - dFs - dV dFc-2c-RC -18 dV dFc ..-tc-Rc dv dV (d) dF (b) dFA dV -TA dFB dV - 218 DF 21 dV dFc --2A-Rc dV (e) None of the above dFc - 2rc - Rc dv
