A column for gas chromatography features: length of packing 52 cm; volume flow rate 0.421 mL/min, volume of the analyte in the mobile phase (VM) 1.57 mL, and volume of the analyte in the stationary phase (VS) 0.321 mL. A chromatogram of a mixture of species A, B, C, and D provided the following data:

we need the questions , i may then you.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
