Carbohydrates
Carbohydrates are the organic compounds that are obtained in foods and living matters in the shape of sugars, cellulose, and starch. The general formula of carbohydrates is Cn(H2O)2. The ratio of H and O present in carbohydrates is identical to water.
Starch
Starch is a polysaccharide carbohydrate that belongs to the category of polysaccharide carbohydrates.
Mutarotation
The rotation of a particular structure of the chiral compound because of the epimerization is called mutarotation. It is the repercussion of the ring chain tautomerism. In terms of glucose, this can be defined as the modification in the equilibrium of the α- and β- glucose anomers upon its dissolution in the solvent water. This process is usually seen in the chemistry of carbohydrates.
L Sugar
A chemical compound that is represented with a molecular formula C6H12O6 is called L-(-) sugar. At the carbon’s 5th position, the hydroxyl group is placed to the compound’s left and therefore the sugar is represented as L(-)-sugar. It is capable of rotating the polarized light’s plane in the direction anticlockwise. L isomers are one of the 2 isomers formed by the configurational stereochemistry of the carbohydrates.

where V(CO2) = volume of gas collected at T = 25 °C and p = 1 atm.
a) Show by graphical means that the reaction obeys a first-order rate law.
(Hint: the easiest way is to convert V(CO2) into the # of mol of gas using the parameter a =
V(CO2). - V(CO2); V(CO2). = volume of gas obtained at the end of the reaction, V(CO2)t =
volume of gas collected at time = t. The ratio (a/ao) is most useful, with ao = a when t = 0.
Key assumptions are that CO2(g) obeys the ideal gas law, and that only an insignificant amount
of this gas remains in solution).
b) Find the rate constant and the time needed to consume 25% of the initially present CCI3CO2H.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F836cff5c-b32e-49bd-a23a-44c38628136f%2Ffdbf7041-f789-4e91-9445-93409786cb69%2Fuae5rx_processed.jpeg&w=3840&q=75)
