What four things are wrong with this solution? the gas phase elementary reaction 2a -— b+ 2c is carried out in a membrane reactor in which there is pressure drop with a = 0,019 kg". an equal molar feed of a and inerts, i, enter the reactor with c 0.4 mol/dm and a total volumetric flow rate of 25 dm /s. only species bed exit through the membrane. the specific reaction rate is ka = 2.5 dm/molkele and the mass transfer coefficient kc = 1.5 dm /kg. s. plot the conversion of a down the membrane reactor containing 50 kg of catalyst.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
