Reaction conversion a. consider the generic reaction a 3b, occurring in a batch reactor. if there are initially 20 g moles of a present, what is the conversion xa if 34 g moles of b are present at the end of the batch reaction process, assuming there is 1.0 mole of b present at the beginning of the batch process? b. consider two parallel reactions a c +d and a → b, both of which are occurring in a cstr. the inlet molar flow of a is fro = 400 gr mole/min, with a volumetric (liquid) flow rate of vo = 20 liters/min. if the steady state effluent from the cstr contains product concentrations of 12.0 g mole/l of cand 3.0 g mole/l of b (assume that there are no product b, c or d in the influent flow), then what is the conversion xa? you should assume the volumetric flow rate is constant (reaction occurs in liquid state).

For a family dinner, jose’s mom baked a loaf of bread. during the meal, his grandmother commented, “this bread is so dense! ” what do you think his grandmother meant by the word dense? you have some ideas regarding density already, but this experiment will enrich your understanding of the relationship between mass, volume and the density of objects. when making measurements in this experiment we will be using si units, the international system of units. the purpose of using si units is to have the ability to communicate and compare data results with other experiments without having to make conversions. measurement symbol si unit length m meter mass kg kilogram volume l liters density kg/l kilograms per liter any calculations that are performed during this experiment will ultimately be reported in scientific notation. recall that scientific notation is extremely important when we have data that is extremely small or large. scientists rely on a standard form of communication to quickly make hypotheses and judgements based on data. what is the density of block a? a0kg/l what is the density of block b? a1kg/l what is the density of block c? a2kg/l what is the density of block d? a3kg/l what is the density of block e? a4kg/l which block is the densest? a5
