Somerization of 1-hexene to 2-hexene occurred in a laboratory reactor over rhodium particles supported on alumina at 150°c and atmospheric pressure. the reaction was a first- order in 1-hexene with a rate constant of 0.15 s'. find the largest pellet size that can be used in an industrial reactor to achieve 75% of the maximum rate. additional data: pore radius of the alumina : 10 nm molecular diffusivity : 0.050 cm's! tortuosity : 4 porosity : 0.5

What is the percentage composition of carbon in the compound ch4

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution. calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
