6.2.5
Sketch and explain qualitatively the Maxwell-Boltzmann energy distribution curve for the fixed amount of gas at different temperatures and the consequences for changes in reaction rates. 
Particles in gases at different temperatures have differen

t kinetic energy, and it is expressed using the Maxwell-Boltzmann distribution curve (below).

The curve proves that the value of kinetic energy varies from one reaction to another. The curve proves the rate of reaction depends on the particles that have values of kinetic energy greater than the activation energy.





6.2.6
Describe the effect of the catalyst  on a chemical reaction. 
A catalyst is a substance increases the rate of reaction without itself going through permanent changes.
It works by providing an alternative route for the reaction.

Without the increase of temperature, the a large amount of particles will have a greater kinetic energy than the activation energy, so there will be a successful collision of particles.

The video where water is used as a catalyst to speed up the reaction between the reactants, Aluminum and Iodine.
