A special alcohol dehydrogenase was recently isolated from a bacterial strain that will catalyze the conversion of alcohol to a special chemical called ASG. At condition of atmospheric pressure and 38oC, researchers found out that the entropy change after reaction (deltaSrxn) is +0.018 kJ/(gmol·K); however they could not quantify the heat of reaction, but only know that the reaction is exothermic. Next step, they try to increase the yield of ASG. Assuming the heat of reaction and the deltaSrxn will not change within a reasonable range of temperature and considering the equilibrium only, would it be more desirable to operate the reaction at 28oC or 48oC?
