Aplug flow reactor (2 m2) processes an aqueous feed (100 liter/min) containing reactant a (cao 100 mmol/iter). this reaction is reversible and represented by: ta (0,04 min )ca- (0,01 min )c 2.1 2.2 2.3. find the equilibrium conversion find the actual conversion of a in the reactor we wish to achieve 97.5% of the equilibrium conversion by adding a cstr in series with the plug flow reactor. what volume must the cstr be in order to achieve this?

Modern pennies are composed of zinc coated with copper. a student determines the mass of a penny to be 2.482 g and then makes several scratches in the copper coaling (to expose the underlying zinc). the student puts the scratched penny in hydrochloric acid, where the following reaction occurs between the zinc and the hcl (the copper remains undissolved): zn(s) + 2 hcl(aq) → h2(g) + zncl(aq)the student collects the hydrogen produced over water at 25 °c. the collected gas occupies a volume of 0.899 l at a total pressure of 79 j mmhg. calculate the percent zinc (by mass) in the penny. (assume that all the zn in the penny dissolves.)
