Acompany plans to run an irreversibly-first-order gaseous reaction with the specific rate constant of 0.01 s in an isothermal flow reactor. pure a will be fed at 1 dm s and the reaction temperature is initially suggested to be set 473 k. conversion must not be less than 50% due to limitation of subsequent separators. a) based on the separator limitation, determine either a plug flow reactor with 6-m length and 6-cm diameter is feasible or not for reaction (1) (13 marks) b) the rate constant of reaction (1) using a catalyst is 0.5 dm2 kgcat s1 determine the practicality of a packed bed reactor (pbr) to run for the reaction when the same separator limitation is applied with the following conditions. feed flow: turbulence density: 100 kg m3 pressure: 2 atm catalyst packing dimension: 6-m length and 6-cm diameter density: 2,00 kg m average particle diameter: 0.5 cm void fraction: 0.4

Temperature and kinetic energy are proportional. a) adirectly b) directly c) indirectly

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl+4h2o enter the elemental symbol. view available hint(s) is reduced

What are the advantages of using the metric system? designed as a decimal system making conversions simpler more accurate system of measurement has prefixes that correspond to an amount to use with all base units used by the entire scientific community
