Attachment 1 Attachment 2 Attachment 3 ATTACHMENT PREVIEW Download attachment 12.b.2.png Thermodynamic Table at 25 .C Pvap atm Substance AH. (kJ/mol) S (J/mol-K) AG; (kJ/mol) CH, OH(1) -239.2 126.8 -166.6 CH, OH(g) -201.0 239.9 -162.3 Consider the equilibrium of methanol vapor and the liquid. CH, OH(1) - CH, OH(g) What is the vapor pressure of the methanol at -30 .C? What is the vapor pressure of the methanol at 40 *C? Pvap = 0.343 atm ATTACHMENT PREVIEW Download attachment 14.b.2.png A critical reaction in the production of energy to do work or drive chemical reactions in biological systems is the hydrolysis of adenosine triphosphate, ATP, to adenosine diphosphate, ADP, as described by the reaction ATP(aq) + H, O(1) -&gt; ADP(aq) + HPO;-(aq) for which AGixn = -30.5 kJ/mol at 37.0 'C and pH 7.0. Calculate the value of AGrxn in a biological cell in which [ATP] = 5.0 mM, [ADP] = 0.70 mM, and [HPO, -] = 5.0 mM. AGrxn = kJ/mol Is the hydrolysis of ATP spontaneous under these conditions? yes O no ATTACHMENT PREVIEW Download attachment 14.e.4.png What would the potential of a standard hydrogen electrode (S.H.E.) be under the given conditions? [H+] = 0.32 M PH, = 3.6 atm T = 298 K E = V
