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?

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
