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?

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
