Answer:
adding heat
stirring
breaking down the cocoa mix into smaller particles
altering amount of water
Explanation:
Reaction rate is a measure of the speed in which a chemical reaction takes place. Some factors affects the rates at which chemical reactions takes place. Some of the factors are:
- Nature of reactants
- Concentration of reactants or pressure if gaseous
- Temperature
- Presence of a catalyst
- sunlight
For the reaction above, we want to consider the factors that can affect the cocoa mix dissolution in water.
- adding heat: temperature is directly proportional to the average kinetic energy of reacting particles. Adding heat will make the cocoa mix dissolve more in the water. This can be by using a hotter water.
- Stirring: stirring also improves the rate of dissolution of the cocoa mix in the water. During stirring, the cocoa mix is brought more in contact with the water. Stirring can help more of the surface area of the cocoa mix to be exposed to the water dissolving action.
- Breaking down the cocoa mix into smaller particles: the surface area proportionally affects the rate of a reaction. If the cocoa mix is broken down, more of the surface area becomes exposed and the reaction proceeds faster.
- altering amount of water: if more water which is the solvent is used, therefore, more solute can be easily dissolved. Altering the amount of water will definitely affect the amount of cocoa mix that can be dissolved.
