Styrene is manufactured by catalytic dehydrogenation of ethylbenzene followed by vacuum distillation to separate styrene from unreacted ethylbenzene. Typical feed conditions for an industrial distillation unit are 77°C (350.6 K) and 100 torr (13.33 kPa). Based on the properties of these substances, and assuming that the hypothesis of ideal gas and ideal liquid solution are suitable for this system at low pressure, estimate the values of the equilibrium ratios K for each component and the relative volatilit

A food product containing 80% moisture content is being frozen. Estimate the specific heat of the product at -8 ° C when 82% of the water is frozen. The specific heat of the dry product is 2.5 kJ / (kg ° C). it is assumed that the specific heat of water at -10 ° C is the same as the specific heat of water at 0 ° C, and the specific heat of ice follows the function Cp es = 0.0062 Tbeku + 2.0649. Cp frozen product = AnswerkJ / kg ° C.

3 Having just invented a new type of calorimeter, Dr. Campbell needs to determine the heat capacity of the calorimeter.  She carries out the following experiment to do this: She puts 20.0 grams of water in her empty calorimeter and it is allowed to stabilize at a temperature of 25.0ºC.  She then adds 35.586 grams of water at a temperature of 83ºC to the calorimeter.  After a few minutes the final temperature of the calorimeter stabilizes at 47.8ºC.   Based on this experiment, what is the heat capacity of her calorimeter assuming units of J/ºC? Enter your answer with at least 3 sig figs.

Evaporator A double-effect evaporator is used to concentrate 5.7 kg/s of 22% NaCl solution at 37°C to 43%. The first and second- effect operates at 20 kPag and 14 kPag, respectively. Saturated steam at 2.3 atm enters at 5 kg/s which leaves the first effect condensed. The surface areas of the two effects are equal. Consider the atmospheric pressure equal to 101,300 Pa. a. Provide the temperature profile of each effect. b. What amounts of vapor leave the effects 1 and 2? Calculate the steam economy. C.

A food product containing 80% moisture content is being frozen. Estimate the specific heat of the product at -6 ° C when 80% of the water is frozen. The specific heat of the dry product is 2 kJ / (kg ° C). It is assumed that the specific heat of water at -10 ° C is the same as the specific heat of water at 0 ° C, and that the specific heat of ice follows the function Cp es = 0.0062 T frozen + 2.0649. Cp frozen product =    kJ / kg ° C.

METAL Suppose you heat a metal object with a mass of 32.9 g to 96.6 °C and transfer it to a calorimeter containing 100.0 g of water at 17.2 °C. The water and metal reach a final temperature of 22.4 °C. What is the specific heat of the metal in J/g-°C?
