The DeltaH^(@)for the mutarotation of glucose in aqueous solution , alpha"-D- glucose (aq)" to beta"-D-glucose (aq)" has been measured in a microcalorimeter and found to be -1.16 kj .mol^(-1) . The enthalpies of solution of the two forms of glucose have been determined to be alpha"-D- glucose (aq)" to alpha"-D-glucose (aq)" DeltaH^(@)=10.72KJmol^(-1) beta"-D- glucose (aq)" to beta-"D-glucose (aq)" DeltaH^(@)=4.68KJmol^(-1) Calculate DeltaH^(@)(in KJ/mol) for the mutarotation of soild alpha"-D-glucose"to soild" beta"-D-glucose:" |
