Delta H=25.5kJ/mol and Delta S= -77.0J/K-mol and assume both do not vary with temperature.Compute for the PCl5 concentration in the following reaction at 78°C equilibrium. PCl3(g) + Cl2(g) ↔ PCl5(g) Kc = 3.572 x 104 PCl3 = 0.238 Cl2 = 0.168Which of the following show a large increase of entropy of the system(refer to image , ther may be multiple options)
- Two students prepared aqueous solutions of LiCl and measured the properties, as shown in the table above. Both students observed that the solid LiCl readily dissolved in H2O. The students drew particle diagrams to explain the changes in the enthalpy and entropy of dissolution for LiCl based on their results and observations. Based on this information, the better particle diagram was drawn by which student, and why is that diagram more accurate? (see attached image) a.) The better particle diagram was drawn by Student 1 because when LiCl dissolves in water, it dissociates into Li+ and Cl− ions causing an increase in entropy. b.) The better particle diagram was drawn by Student 1 because when LiCl dissolves in water, it dissociates into Li+and Cl−ions indicating that the dissolution of LiCl is exothermic. c.) The better particle diagram was drawn by Student 2 because it shows that LiCl does not dissociate, resulting in a decrease in entropy for the dissolution of LiCl.…Compute for the PCl5 concentration in the given reaction at 78°C equilibrium.
