4. Be sure to answer all parts. Predict whether the entropy change is positive or negative for each of the following reactions KCIO6) 2 KCIO()+0.2) O positive O negative positive O negative
Short Answer: (4 points each) 1.) Predict whether the entropy change is positive or negative for each of the following reactions. GIVE YOUR REASON FOR YOUR PREDICTIONS a) 2KC1O4(s) → 2KCIO3() + O2(8) b) H2O → H2O) c) 2Na(3) + H2O → 2NaOH(aq) + H2() d) N2(g) → 2N) 2.) State whether the sign of the entropy change expected for each of the following processes will be positive or negative, and EXPLAIN YOUR PREDICTIONS. a) PC130) + Cl2(e) → PCls(s)...
Determine the standard entropy change of the universe when 0.2 mol of NH,NO3 is produced, NH4+ (aq) + NO3-(aq) --NH.NO3(s), given the following information. (answer in J/K) Substance NH.NO3(s) AH!"(kJ/mol) SºU/molK) -365.6 151.1 -132.5 113.4 -205.0 146.4 NH" (G) NO3(aq) Answer: Check
A scientist measures the standard enthaply change for the following reaction to be 80.4kJ NH4Cl(aq)=NH3(g)+HCl(aq) Based on this value and the standard enthalpies of formation for the other substances, the standard enthaply of formation of HCl (aq) Use the References to access important values if needed for this question A scientist measures the standard enthalpy change for the following reaction to be 80.4 kJ. NH Cl(aq) +NH (9) + HCl(aq) G Based on this value and the standard enthalpies of...
3) Predict whether the change in entropy is positive, negative, or zero for each of the following reactions at 298 K, and explain your reasoning (2 pts each. 8 pts total): 1.4 Fe(s) + 3 O2(g) → 2 Fe:O:(s) b. O(g) + ( ) → O.(g) NH,Cl(s) » NH(g) + HCl(g) d. Hz(g) + Cl:(g) → 2 HCI c.
Predict, using the intuitive ideas about entropy,whether Ssys will bepositive, negative, or essentiallyzero for each of the following:a.Ca(OH)2(s) + CO2(g) CaCO3(s) +H2O(g)b.CuSO4(s) Cu2+(aq)+SO42-(aq)c.2HCl(g) + Br2(l) 2HBr(g) + Cl2(g)d.SO2(g) + 1/2 O2(g) SO3(g)e.Cu2+(aq) + 4NH3(aq) Cu(NH3)42+(aq)I used the equationn(gas)=(sum of coefficients of gases in theproducts)-(sum ofcoefficients of gases in the reactants). This is what Ifound:a.1-1=0b.0-0=0c.3-2=1d.1-1.5= -0.5e.0-0=0-The sign of Scorresponds to the sign of n. Therefore, I know C must have a positive Sand D must have a negative S.-Neither B nor...
