PLEASE HELP!!
in an experiment, sulfuric acid reacted with different volumes of sodium thiosulfate in water. A yellow precipitate was formed during the reaction. A cross drawn at the base of each flask became gradually invisible due the formation of this yellow precipitate. The time taken for the cross to become visible was recorded. A partial record of the experiment is shown.

Based on your knowledge of factors that affect the rates of chemical reactions, predict the trend in the last column of the experimental record. use complete sentences to explain the trend you predicted. You do not have to determine exact values of time; Just describe the trend you would expect (increase or decrease) and why it occurs.

The time for the reaction will keep increasing as water levels increase.

Concentration and rate of reactions

Concentration is one of the factors that affect the rate of reactions. It affects both reversible and irreversible reactions.

An increase in the concentration of reactants increases the rate at which products are formed from reactions. A decrease in the concentration of reactants, on the other hand, decreases the rate of reactions.

From the table, the concentration of sodium thiosulfate keeps decreasing downward. This is because the volume of water being added kept increasing.

Thus, the time taken for the reactions will keep increasing as we move downward on the table.
