Surface tension increases by increasing the intermolecular forces.

<h3>What is intermolecular forces?</h3>

The electromagnetic forces of attraction or repulsion that act between atoms and other types of nearby particles, such as atoms or ions, are examples of intermolecular forces (IMFs), also known as secondary forces.

Between molecules, intermolecular forces are at work. In contrast, molecules themselves exert intramolecular pressures. In comparison to intramolecular forces, intermolecular forces are weaker. Intermolecular forces include things like the London dispersion force, dipole-dipole interaction, ion-dipole interaction, and van der Waals forces.

Intermolecular forces come in five flavors: ion-induced dipole forces, dipole-induced dipole forces, induced dipole forces, and dipole-dipole forces. Ions and polar (dipole) molecules are held together by ion-dipole forces.

juin [17]

Answer:

The time decreases steadily

Explanation:

We know that the rate of chemical reaction is defined as how fast or slow a chemical reaction proceeds. Hence a chemical reaction is said to proceed at a faster rate if it takes a lesser time for the reaction to get to completion.

There are certain factors that affects the rate of reaction, prominent among them is the concentration of reactants. Concentration simply means the amount of substance in a system.

Taking a look at the table given in the question, we will realize that the volume of HCl remained constant, the volume of thiosulphate increased steadily while the volume of water decreased steadily. Remember that concentration increases when less water is added to the system. This implies that the reactant concentration increases steadily. Hence, according to the collision theory, particles collide more frequently and the rate of reaction increases.

As the rate of reaction increases, it now takes a lesser time for the reaction to get to completion (indicated by the disappearance of the cross). Hence as we move down the table, it takes lesser and lesser time for the cross to disappear. This means that the column for time will decrease steadily.
