(Multiple reactions with heat effects). Styrene can be produced from ethylbenzene by the following reaction: 2 H styrene ne ethylbenze + ↔ (1) However, several irreversible side reactions also occur: ethylene benzene ne ethylbenze + → (2) methane toluene H ne ethylbenze 2 + → + (3) [J. Snyder and B. Subramaniam, Chem. Eng. Sci., 49, 5585 (1994)]. Ethylbenzene is fed at a rate of 0.00344 kmol/s to a 10.0- m 3 PFR reactor along with inert steam at a...

Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...
