The elementary irreversible gas phase reaction a → b + c is carried out in a pfr packed with catalyst. pure a enters the reactor at a volumetric flowrate of 20 dm3/s at a pressure of 10 atm and 450k part i- adiabatic operation a) plot the conversion and temperature down the plug flow reactor until 80% conversion is achieved. b) calculate the amount of catalyst required to achieve 80% conversion. ha--70 k/mol hrs -50 kj/mol hrc-40 kj/mol (tr 273 k) cpa-40 j/mol. k cp 25 j/mol. k cpc=15 /mol-k 0.133e sp r1450-ti kg cat s with e = 31.4 kl/mol part ii consider that the heat is removed by a heat exchanger jacketing the reactor. the flowrate of coolant through the jacket is sufficiently high so that the ambient exchanger temperature is constant at 50°c u 100 w/m2.k d-10 cm po-5 g/cm a) plot the conversion and temperature down the plug flow reactor until 80% conversion is achieved. discuss the effect of feed temperature on the temperature profile and conversion. b) calculate the amount of catalyst required to achieve 80% conversion.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
