Chlorocyclohexane reacts with sodium cyanide (NaCN) in ethanol to give cyanocyclohexane. The rate of formation of cyanocyclohexane increases when a small amount of sodium iodide is added to the solution. Explain this acceleration in the rate.

Consider an aerobic production of acetic acid (P) from ethanol (S) using Acetobacter aceti bacteria. Acetobacter aceti bacteria are added to vigorously-aerate medium containing 16 g/L ethanol. After 16 hours, the ethanol concentration is 4 g/L and 8 g/L acetic acid is produced. What is the yield coefficient (Y P/S)?

Hydrodealkylation is a process in which side chain alkyl groups (like methyl) are removed from aromatics by reaction with hydrogen. The following reactions take place in the reactor: E1 C6H₂CH3 + H₂C6H6 + CH4 C6H4(CH3)2 + H₂C6H5CH3 + CH4 C6H3 (CH3)3 + H₂C6H4(CH3)2 + CH4 In addition, an unwanted side reaction occurs, in which benzene dimerizes to form diphenyl [C6H5C6H5] E4 2 C6H6C6H5C6H5 + H₂ A process stream containing 5 mol % benzene [C6H6], 20 mol% toluene [C6H₂CH3], 35 mol% xylene [C6H4(CH3)2], and 40 mol % pseudocumene [C6H3 (CH3)3] is fed to a hydrodealkylation plant. This process stream is mixed with hydrogen gas in 5:1 gas-aromatics ratio before being fed to the reactor. A condenser separates hydrogen and methane from the other reactor products (lumped as aromatics). Feed 2.2.2. ?B BTXP ?T ? X ?P Reactor Hydrogen Gas ? H₂ Light Gases ?
