Question

Solve the following independent questions. a) Construct the hypothetical path for the calculation of the change of the enthalpy for the following process. You don't need to calculate any number! Just write all the steps and equations that should be used for the calculations. (10 pts). 0-\text { Xylene }\left(s, 20^{\circ} \mathrm{C}, 3 \text { atm }\right) \rightarrow 0-\text { Xylene }\left(v, 20^{\circ} \mathrm{C}, 2 \text { atm }\right) b) Calculate the change of the enthalpy if 25g of liquid acetone changes temperature from 40°C to 20°C. (10 pts) c) Construct the enthalpy table for the process shown below. Specify clearly the references. No calculation is needed. (10 pts)
