Stacy runs a paper chromatography experiment

Stacy runs a paper chromatography experiment using the same ink, but two different solvents. Using solvent A results in the ink separating into three bands, but solvent B does not carry the ink away from the original spot. Which of the following could explain the results?

- The Ink was a mixture, but only in solvent A

-Solvent A was not a good mobile phase because it could not dissolve the ink

-The ink was a pure substance and dissolved in both solvents

-Solvent B was not a good mobile phase cause it could not dissolve the ink

consider the reaction below.

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?
