Areactor that has a volume of 1.2 m3 is operated at 120oc to degrade a gaseous starting material into a useful gaseous product with stoichiometry 2a → p in a constant volume system.
(a) if the rate constant for a is 0.13 min-1 what is the total system pressure (pt) after 10 min if the initial pressure of a (pa0) is 5 atm.
(b) calculate the partial pressure of a (pa) after 10 min and the conversion.
(c) what would be the volumetric feed rate into the reactor if plug flow conditions could be assumed?

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
