Which of these factors will cause a solid solute to dissolve faster? increasing the air temperature increasing the amount of solute increasing the amount of solvent increasing the surface area of solute

1. increase in air temperature

2. increaing the surface are of the solute

Explanation:

A substance that is present in smaller quantity as compared to the solvent in a solution is known as a solute.

When we add more amount of solute into a solvent then it means more number of solute particles come in contact with the solvent particles. As a result, more number of collisions take place due to which there will be increase in rate of reaction.

Also, when we increase the surface area of solute then it means more number of solute particles will come in contact with the solvent. Hence, there will increase in rate of reaction.

When we increase the temperature of reaction mixture then its molecules will gain more kinetic energy due to which there will be more number of collisions and hence, eventually rate of reaction also increases.

But if we increase the air temperature then there will be no change in number of collisions or no gain in kinetic energy will take place between the solute and solvent particles.

Thus, we can conclude that factors which will cause a solid solute to dissolve faster are as follows.
