1. The heat of vaporization of n-butane and water at 25° C are 19.2 kJ/mol and 44 kJ/mol, respectively. What is the standard enthalpy of the following reaction? C,H10 (1) +02 (g) → 4 CO2 (g) + 5 H,0 (g) Calculate the rate of enthalpy change if 2400 mol/s of CO2 is produced in the reaction and the reactants and products are at 25 °C.

How would the increase in entropy be used as a measure of the irreversibility of a process? 21. How is the entropy and probability interrelated? 22. “A knowledge of the entropy change provides information concerning the structural changes accompanying a process". Comment on this. 23. State the third law of thermodynamics. How does it follow from the statistical explanation for entropy? EXERCISES 4.1 Calculate the minimum work required to produce 10 kg ice cubes from water initially at 273 K. Assume that the surroundings are at 300 K. The latent heat of fusion of water at 273 K = 333.5 kJ/kg. 4.2 A 800 MW thermal power plant uses steam at 600 K and discards heat to a river at 295 K. Determine the heat discarded to the river if the thermal efficiency of the plant is 70 per cent of the maximum possible value. 4.3 The overhead vapour from a distillation column is taken to a…

What is the Joule experiment? Why is it important? What does it prove?

Can you explain the set up of how to solve for the mass flow rate of position 3, the flow rate leaving the condenser?  I do not require the entire solution, just the set-up. This is a distillation column problem, and all enthalpies are provided, almost all mass fractions are provided as well, but no flow rates were given.

Which of the following situations can we consider a recycle stream for a process with reacting units? a. The reactants are highly miscible with the products. b. The feed is a mixture of valuable compounds known to be toxic to humans. c. Separation of reactants from the product requires state-of-the-art technology. d. Raw feed to the reactor is extremely valuable and is found to be non-toxic to humans.
