This is an open system with constant height and velocity. Put 100 kmol/s of H2 (H = 5141 kJ/kg) and 50 kmol/s of O2 (H = 4365 kJ/kg)in the system and let them react to form 100 kmol/s of H2O (H = 4929 kJ/kg).How much heat was added to the system to perform this reaction?

Steam is used to cool a polymer reaction. The steam in the steam chest of the apparatus is found to be at 250.5°C and 4000 kPa absolute during a routine measurement at the beginning of the day. At the end of the day the measurement showed that the temperature was 650°C and the pressure 10,000 kPa absolute. What was the internal energy change of 1 kg of steam in the chest during the day? [steam tables are your friend for this problem!]

4. Will phase change happens to water at 1 atm. as the temperature rises from - 15°C to 60°C?Support your answer.

A chemical engineer is studying the two reactions shown in the table below. In each case, she fills a reaction vessel with some mixture of the reactants and products at a constant temperature of 100.0 °C and constant total pressure. Then, she measures the reaction enthalpy AH and reaction entropy AS of the first reaction, and the reaction enthalpy AH and reaction free energy AG of the second reaction. The results of her measurements are shown in the table. Complete the table. That is, calculate AG for the first reaction and AS for the second. (Round your answer to zero decimal places.) Then, decide whether, under the conditions the engineer has set up, the reaction is spontaneous, the reverse reaction is spontaneous, or neither forward nor reverse reaction is spontaneous because the system is at equilibrium. AH = 181. kJ J AS = 530. K N, (g) + 0,(g) → 2NO(g) AG = ||| kJ Which is spontaneous? this reaction the reverse reaction neither AH = 92. kJ J AS = K 2N H, (g) → N, (g) + 3H, (g) AG…

with a energy of 87 kW, how much 40 bar saturated steam is needed in kg per min to heat up acetonitrile at a final temp of 220°C. The inital temp is 20°C. hint: use your steam table to find the correct answer.

A reaction occurs between hydrogen gas and chlorine gas. This causes their container to expand from 2 L to 12 L. The expansion causes the container to do 14 J of work. What was the pressure inside the container? Be sure to show all of your work and include the correct units.
