This indicates that G = H - TS > 0. From inspection of the reaction, it can be concluded that S > 0 (a gas evolves). Consequently, H > TS explains why the reaction does not occur.According to Table 1, what is the concentration of the glucose in the blood from which the diluted sample was taken?A.60 mg/dLB.90 mg/dLC.120 mg/dLD.150 mg/dL - ANSWER D. 150 mg/dLFrom Table 1, the glucose concentration in the diluted sample is (0.20/0.24) 6.0 mg/dL= 5.0 mg/dL. The blood then has a glucose concentration of 30 5.0 mg/dL = 150 mg/dL.Which of the following oxidative transformations is unlikely to occur?A.A primary alcohol to an aldehydeB.A tertiary alcohol to a ketoneC.An aldehyde to a carboxylic acidD.A secondary alcohol to a ketone - ANSWER B.
