Following enthalpy changes are given:
`alpha-Dglucose (s) rarr alpha-D glucoes (aq), DeltaH = 10.72 kJ`
`beta-D glucose (s) rarrbeta-D glucose(aq), DeltaH = 4.68kJ`
`alpha-D glucose (aq) rarr beta-D glucose(aq), DeltaH =1.16 kJ`
Calculate enthalpy change in
`alpha-D glucose (s) rarr beta-D glucose (s)`

Options

A. `14.24 kJ`
B. `16.56 kJ`
C. `7.2 kJ`
D. `4.88 kJ`

Explanation

To calculate the enthalpy change for the reaction:

\[ \text{α-D glucose (s)} \rightarrow \text{β-D glucose (s)} \]

we can use Hess's Law, which states that the total enthalpy change for a reaction is the sum of the enthalpy changes for the individual steps of the reaction.
