(C2) Hello! I just want to ask for help whether the answers in the given pictures are correct. If it's not, please help me recheck and resolve it. Please refer to the given pictures below for the answers and questions. Please read the instructions and directions very carefully. Double and triple check your answers, previous tutors got it wrong. NOTE: Type only your answers. Please do not handwritten your answers. Make sure your formulas, solutions and answers' format are all correct. A. Read each item carefully and choose the letterof the correct answer.1. Which of the following statements best describesthe Second Law of Thermodynamics?A. The internal energy of the universe is constant.B. Energy can neither be created nor destroyed.C. At absolute zero, the entropy of a crystal isconsidered to be zero.D. When an isolated system undergoes aspontaneous change, the entropy of the systemincreases.2. Which of the following represents a spontaneousprocess?A. AS<0B. AS-0C. AG>0D. AG<03. Which of the following has the most entropy?A. an empty classroomB. a tennis ball inside a boxC. a flock of birds flying in V formationD. a crowd of people on the streets of Santa Rosa CityB. Predict whether AS is positive or negative forthe reaction: N₂(g) + O2(g) → 2NO(g)C. Which has greater entropy? 1mole of NaCl(5) or 1mol of HCl(g)Expert SolutionStep 1Entropy is a calculate of the uncertainty or disarray of a system. The value of entropy based on the mass of a system. It isindicated by the letter S and has units of joules per kelvin. Entropy can have a non-inverse or inverse value.Step 21. Which of the following statements best describes the Second Law of Thermodynamics?Answer: Option D: When an isolated system undergoes a spontaneous change, the entropy of the system increases.Reason:a) For T = Ok Entropy s=0 (wrong)b) First law of thermodynamicsc) For T = 0k Entropy s-positive for crystalline substance (wrong)Step 32. Which of the following represents a spontaneous process?Answer: Option D) AG<0Reason:Spontaneous reaction - free energy should be thereAG=AH-TASAG <0Remaining option are all wrongStep 43. Which of the following has the most entropy?Answer: Option D. a crowd of people on the streets of Santa Rosa CityReason:Entropy is a calculate of the uncertainty or disarray of a system. The value of entropy based on the mass of a system. It isindicated by the letter S and has units of joules per kelvin. Entropy can have a non-inverse or inverse value. (A). Prediction of the sign of AS is positive or negative for the reaction: N₂ (g) + O₂ (g)2NO (g) :-→>>Entropy (S) is the extensive property of the system which measure the degree of disorderor randomness of the matter. Entropy increases from solid to liquid and liquid to gasbecause degree of disorder increases.Now,The given reaction is :N₂ (g) + O₂ (g) 2NO(g)Here,Number of moles of gaseous reactants = 1 + 1 = 2 molesNumber of moles of gaseous products = 2 molesBecause, number of moles of gases on both sides are equal, so sign of change in entropy,AS cannot be predicted. It can be calculated by using the formula as :AS = [Sum of entropy of products] - [Sum of entropy of reactants]Then,AS = [2 x Sº of NO (g)] - [Sº of N₂ (g) + Sº of O₂ (g)]= [2 x 210.8 J/K] - [191.6 J/K + 205.2 J/K]= 421.6 J/K - 396.8 J/K= + 24.8 J/KTherefore. sign of AS is positive for this reaction.Step 3B. Which has greater entropy? 1 mole of NaCl (s) or 1 mole of HCl (g) :-1 mole of HCl has the greater entropy than 1 mole of NaCl (s), because HCl is gas whileNaCl is solid. So, due to more randomness of HCl (g) as compared to NaCl (s), 1 mole ofHCl (g) has greater entropy.

Energy of universe is constant. Energy can neither be created or nor be destroyed is stated by first…
