The stronger intermolecular force has been found in glycerol with high viscosity as it has a larger molar mass. Thus, option A is correct.
The viscosity has been defined as the resistance of the fluid to the deformation. The viscosity has been dependent on the molar mass and intermolecular force in the compounds.
The stronger intermolecular force and molar mass tend to have more resistance to the deformation and thus have more viscosity.
The intermolecular force present in glycerol and water is hydrogen bonding. The molar mass of glycerol has been higher than water, this tends to have more resistance and viscosity.
Thus, glycerol has high viscosity as it has a larger molar mass. Thus, option A is correct.

<u>Answer:</u> The for the reaction is -297 kJ.
<u>Explanation:</u>
Hess’s law of constant heat summation states that the amount of heat absorbed or evolved in a given chemical equation remains the same whether the process occurs in one step or several steps.
According to this law, the chemical equation is treated as ordinary algebraic expressions and can be added or subtracted to yield the required equation. This means that the enthalpy change of the overall reaction is equal to the sum of the enthalpy changes of the intermediate reactions.
The given chemical reaction follows:
The intermediate balanced chemical reaction are:
(1)
(2)
The expression for enthalpy of the reaction follows:
Putting values in above equation, we get:
Hence, the for the reaction is -297 kJ.
