Mark the correct statements. (Select all that apply.) O [The reaction 2H20(g) → 2H2(g) + O2(g) is expected to have a positive value of ASº.] O [If a sample of pure ozone changed to oxygen at constant T and P, the entropy of the sample would decrease.] O [For the process H20(1) → H20(s) occurring at 0°C and 1 atm, the sign of AS is negative.] O [The value of AS for the process CHC13(1) – CHC13(g) is negative.] O [The reaction CH4(g) + 202(g) → CO2(g) + 2H2O(g) has a negative value of ASsurr-]
1) Predict the sign (+ or -) of the entropy for the system and justify your answer. H2 (g) + ½ O2 (g) → H2O (l) 2) Calculate the entropy change for each of the above using your data tables. H2 (g) + ½ O2 (g) → H2O (l) ΔS° =? Note: Please answer number 1 and 2 Thank you.
a) Formulate the second law of thermodynamics. b) Consider the statements below. Answer them and give brief explanations. a. An explosive (e.g. C7H5N3O6) reacts with oxygen, the result is CO2 (g), H2O (g) and N2 (g). Is there an increase or decrease of Entropy after the reaction occurred? b. Colloquially, people say that during the cold months of the year, the “cold” is creeping into the warmer house. Is this statement true considering the 2nd law?
