As a reactant gets used up in a chemical reaction, the reaction rate generally decreases. This is because the concentration of the reactant decreases, leading to fewer collisions between reactant molecules. Consequently, the overall frequency of successful collisions diminishes, slowing down the reaction until the reactant is consumed or the reaction reaches equilibrium.
The rate of the reaction slows down
The rate of the chemical reaction will decrease because oxygen is one of the reactants required for the reaction to occur. With less oxygen available, the reaction will proceed at a slower pace.
When a catalyst is used in a chemical reaction, the reaction rate typically increases. This is because the catalyst provides an alternative reaction pathway with lower activation energy, allowing the reaction to proceed more quickly. Catalysts themselves are not consumed in the reaction and can be reused.
In brief, the reaction rate increases. When there are more collisions, the more probability to collide them in the proper direction. The overall reaction will come to the equilibrium in a lesser time.
Heating a chemical reaction increases the kinetic energy of the reactant molecules, leading to more frequent and energetic collisions. This typically results in a faster reaction rate and can sometimes lead to different products being formed due to changes in activation energy and reaction pathways.

The rate decreases as reactants are used up.
the rate of the operation gets higher
The reaction rate depends on the order of the reaction. In general (except for zero order), as the reaction progresses, the rate decreases with time.

As a reactant gets used up in a reaction, the rate of the reaction may slow down since there are fewer reactant molecules available to react. This can lead to a decrease in the production of products until all the reactant is fully consumed.

If the activation energy decreases, the reaction rate typically increases because a lower activation energy makes it easier for the reactant molecules to overcome the energy barrier and form products. This allows the reaction to proceed more rapidly at a given temperature.
