b. increase in surface area

<h3>Further explanation</h3>

Given

Speeding up a chemical reaction

Required

Factors used to speed up reactions

Solution

There are several factors that influence reaction kinetics :  

1. Concentration  

2. Surface area  

3. Temperature  

4. Catalyst  

5. Pressure  

6. Stirring  

Temperature is related to the kinetic energy of the particles. Heat is absorbed causes the particles of matter to move faster so that the reaction can take place faster

The enlarged surface area of the reactants causes more particles to react with other particles.

50 g square block of sulfur can be broken into small pieces or powdered so that more particles come into contact with each other

When a pure sample of KNO3(s) spontaneously dissolves in water at room temperature, the solution becomes quite cold to the touch
jekas [21]

The enthalpy of the solution is <u>positive </u>and the entropy is <u>positive</u>.

Potassium trioxonitrate (V) KNO₃(s) is a strong oxidizing solid substance that when dissolved in water changes to aqueous solution.

In its aqueous solution state, the randomness of molecules increases as a result of that the entropy will also increase leading to the positive state of the entropy.

Similarly, provided that the solution becomes quite cold to the touch, the enthalpy is also in it positive state.

Therefore, we can conclude that the enthalpy of the solution is <u>positive </u>and the entropy is <u>positive</u>.
