Answer: Bonds between atoms break and new bonds form.
Explanation:
A chemical reaction takes place when bonds between atoms of the reactants break and new bonds form in the product.
An endothermic chemical reaction requires energy to break the bonds and an exothermic reaction releases energy.
Reactants go into a reaction and products come out.
Chemical reaction:
A + B ⇒ AB
where A and B are reactants and AB is the product. Atomic bonds of A and B break to form new bonds in the product AB

Explanation:
K in chromatography is defined as a partition coefficient. It is an equilibrium constant that determines the measure to which the solutes partition between two phases.
K = Cm/Cs
where Cm is solute concentration in mobile phase
Cs is solute concentration in stationary phase
When K is more, then it implies that the solute concentration in the mobile phase is more in chromatography test.
