The time for the reaction will keep increasing as water levels increase.
<h3>Concentration and rate of reactions</h3>
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.

At room temperature oxygen, is present in the gas phase.
A gas is defined as a substance which is characterized by the rapidly movement of molecules which are widely separated. The shape and volume of gas is not definite that is they take on the shape of the container in which it is placed. The gas molecules have minimum inter-nuclear attractions and thus have high kinetic energy.
Thus, the sentences that describes oxygen at room temperature are:
- It has no definite volume and takes the shape of its container.
- Its particles move fast enough to overcome the attraction between them.
- It has more energy than it would be at a cooler temperature as the kinetic energy is directly proportional to the temperature that is kinetic energy increases on increasing the temperature.
A loss<span> of </span>kinetic energy<span> in the atoms or molecules of a </span>sample of matter<span> will result in the cooling of the sample.</span>
