Concept explainers
(a)
Interpretation: The Vitamin which acts as a water-soluble antioxidant has to be stated.
Concept introduction: Some vitamins are fat soluble and some are water soluble. Water soluble vitamins are B and C. All of the B vitamins serve as precursors for enzyme cofactors. Vitamin C is not an enzyme cofactor precursor.
(b)
Interpretation: The Vitamin which acts as a fat-soluble antioxidant has to be stated..
Concept introduction: Fat soluble vitamins are A, D, E and K and rest all vitamins are water soluble. Fat soluble vitamins can act as anti oxidants.
(c)
Interpretation: The Vitamin which is involved in process of vision has to be stated.
Concept introduction: Normal dietary intake provides a person with the precursor forms of vitamin A. Vitamin A provides visual pigment rhodopsin. The conversion of light energy into nerve impulses that are sent to the brain involves the participation of rhodopsin.
(d)
Interpretation: The Vitamin which is involved in the formation of collagen has to be stated.
Concept introduction: Vitamin C is a water soluble vitamin. It is involved in the formation of collagen.

- The table includes macrostates characterized by 4 energy levels (&) that are equally spaced but with different degrees of occupation. a) Calculate the energy of all the macrostates (in joules). See if they all have the same energy and number of particles. b) Calculate the macrostate that is most likely to exist. For this macrostate, show that the population of the levels is consistent with the Boltzmann distribution. macrostate 1 macrostate 2 macrostate 3 ε/k (K) Populations Populations Populations 300 5 3 4 200 7 9 8 100 15 17 16 0 33 31 32 DATO: k = 1,38×10-23 J K-1arrow_forwardDon't used Ai solutionarrow_forwardIn an experiment, the viscosity of water was measured at different temperatures and the table was constructed from the data obtained. a) Calculate the activation energy of viscous flow (kJ/mol). b) Calculate the viscosity at 30°C.

The dominant macrostate or configuration of a system is the macrostate with the greatest weight W. Are both statements correct?arrow_forwardFor the single step reaction: A + B → 2C + 25 kJ If the activation energy for this reaction is 35.8 kJ, sketch an energy vs. reaction coordinate diagram for this reaction. Be sure to label the following on your diagram: each of the axes, reactant compounds and product compounds, enthalpy of reaction, activation energy of the forward reaction with the correct value, activation energy of the backwards reaction with the correct value and the transition state. In the same sketch you drew, after the addition of a homogeneous catalyst, show how it would change the graph. Label any new line "catalyst" and label any new activation energy.arrow_forward
