1. The following reaction goes to 80% completion in a CSTR. A and B are fed to the reactor at rates of 2 mol/s and 3 mol/s respectively at a temperature of 370C. Specific heats (in J/mol-K) of A, B, C and D are 200, 150, 220 and 180 respectively.
The reactor is jacketed by water at a temperature of 200C. The overall heat transfer coefficient has been estimated at 300 J/(m2.s.K), while the heat transfer area is 0.75 m2. Mixing is ensured through an agitator, which contributes a work of 12 KW to the reactor. The heat of reaction is -30,000 J/mole of A at 300 K. Calculate the steady state temperature in the reactor.
Calculate the molarity of each of these solutions. a. A 5.623-g sample of NaHCO3 is dissolved in enough water to make 250.0 mL of solution. b. A 184.6-mg sample of K2Cr2O7 is dissolved in enough water to make 500.0 mL of solution.

A strip of metallic scandium, Sc, is placed in a beaker containing concentrated nitric acid. A brown gas rapidly forms, the scandium disappears, and the resulting liquid is brown-yellow but becomes colorless when warmed. These observations best su..
A continuous filter is used to separate a clear filtrate from alumina particles in a slurry. The slurry has 30% by weight of alumina (specific gravity of alumina = 4.5). The cake retains 5% by weight of water. For a feed stream of 1000 kg/hr, determi..
