Answer:
Decreasing the temperature will shift the equilibrium leftwards towards reactants.
Explanation:
Hello!
In this case, since the reaction between chromate anions and hydrogen ions yields dichromate anions, water and heat, we can infer this is an exothermic reaction by which heat is released (remember in endothermic reactions heat is absorbed as a reactant), it means that considering the LeChatelier’s which states that increasing the temperature of an exothermic reaction shifts the equilibrium leftwards since heat is a product, otherwise (decreasing the temperature) the equilibrium will be shifted rightwards.
Therefore, decreasing the temperature is the perturbation that will shift the equilibrium leftwards towards the reactants.

The two properties of the ink components that determine their movement along the chromatography paper/fabric are:
the solubility of ink constituent in chemical solvent.
the mixture of colour constituents in the ink.
Explanation:
Chromatography is the process in which the chemicals of the mixture are separated on the basis of constituents.
Capillary action let the colors of ink separate into their constituents. When ink is subjected to solvents it gets dissolve and gets separated.
The property of ink that led to determine their movement is:
Ink is made of many dyes of different colours, pigments etc.
The chemicals that has the best solubility in the chemical will move up on the chromatography paper and fabric.
D. It slows down
It slows down because the water keeps its from sinking
