- Over what temperature range are the reactions in Problem 40 spontaneous?arrow_forwardCisplatin [cis-diamminedichloroplatinum(II)] is a potent treatment for certain types of cancers, but the trans isomer is not effective. What is the equilibrium constant at 298 K for the transformation of the cis to the trans isomer? Which is the favored isomer at 298 K, the cis or the trans isomer?arrow_forwardElemental boron, in the form of thin fibers, can be made by reducing a boron halide with H2. BCl3(g) + 32 H2(g) B(s) + 3 HCl(g) Calculate rH, rS, and rG at 25 C for this reaction. Is the reaction predicted to be product-favored at equilibrium at 25 C? If so, is it enthalpy- or entropy-driven? [S for B(s) is 5.86 J/K mol.]arrow_forward
- Calculate rH and rS for the reaction of tin(IV) oxide with carbon. SnO2(s) + C(s) Sn(s) + CO2(g) (a) Is the reaction product-favored at equilibrium at 298 K? (b) Is the reaction predicted to be product-favored at equilibrium at higher temperatures?arrow_forwardFor each pair of items, tell which has the higher entropy and explain why. (a) Item 1, a sample of solid CO2 at -78°C, or item 2, CO2 vapor at 0°C (b) Item I, solid sugar, or item 2, the same sugar dissolved in a cup of tea (c) Item 1, a 100-mL sample of pure water and a 100-mL sample of pure alcohol, or item 2, the same samples of water and alcohol after they have been poured together and stirredarrow_forwardEstimate the temperature range over which each of the following reactions is spontaneous. (a) 2Al(s)+3Cl2(g)2AlCl3(s) (b) 2NOCl(g)2NO(g)+Cl2(g) (c) 4NO(g)+6H2O(g)4NH3(g)+5O2(g) (d) 2PH3(g)3H2(g)+2P(g)arrow_forward
- Without doing any calculations, predict the sign of rS for the following reaction: Zn(s) + 2 HCl(aq) ZnCl2(aq) + H2(g) (a) rS 0 (b) rS = 0 (c) rS 0arrow_forwardExplain why each of the following statements is incorrect. (a) Entropy increases in all spontaneous reactions. (b) Reactions with a negative free energy change (rG 0) are product-favored and occur with rapid transformation of reactants to products. (c) All spontaneous processes are exothermic. (d) Endothermic processes are never spontaneous.arrow_forwardConsider the following diagram of free energy (G) versus fraction of A reacted in terms of moles for the reaction 2A(g) B(g). Before any A has reacted, PA = 3.0 atm and PB = 0. Determine the sign of G and the value of Kp. for this reaction.arrow_forward
- Consider the reaction N2O2(g) 2NO2(g) where PNO2=0.29 atm and PN2O4=1.6. For this reaction at these conditions. G = 1000 J and G = 6000 J. Which of the following statements about this reaction is(are) true? a. The reverse reaction is spontaneous at these conditions. b. At equilibrium. PN2O4 will be greater than 1.6 atm. c. The value of K for this reaction is greater than 1. d. The maximum amount of work this reaction can produce at these conditions is 6000 J. e. The reaction is endothermic.arrow_forwardYeast can produce ethanol by the fermentation of glucose (C6H12O6), which is the basis for the production of most alcoholic beverages. C6H12O6(aq) 2 C2H5OH() + 2 CO2(g) Calculate rH, rS, and rG for the reaction at 25 C. Is the reaction product- or reactant-favored at equilibrium? In addition to the thermodynamic values in Appendix L, you will need the following data for C6H12O6(aq): fH = 1260.0 kl/mol; S = 289 J/K mol; and fG = 918.8 kl/mol.arrow_forwardAt room temperature, the entropy of the halogens increases from I2 to Br2 to Cl2.
