A positive catalyst will increase the rate of a chemical reaction
A positive catalyst is a catalyst that is used to accelerate the reaction.
The catalyst makes activation energy more lace
There are several factors that influence reaction kinetics, namely:
1. Concentration
the greater the concentration of the reactants, the faster the reaction will be
2. Surface area
the more surface area of the reaction substance is faster
3. Temperature
at higher temperatures the rate of chemical reactions is faster
4. Catalyst
catalyst increases reaction speed
5. Pressure
an increase in pressure will reduce the volume, so the number of collisions between molecules is greater because the distance between molecules is more close together, so that in the end the reaction takes place faster
6. Stirring
stirring can enlarge the surface area and accelerate collisions
If we see the answer choices that exist then
a. positive catalyst and d. negative catalyst
The catalyst itself does not participate permanently in the reaction that takes place because at the end of the reaction it will be recovered
The catalyst makes activation energy more lace. The activation energy itself is minimal energy that must be possessed or given to a particle so that the collision produces a reaction
A positive catalyst is a catalyst that is used to accelerate the reaction while a negative catalyst is a catalyst called an inhibitor which is a catalyst that functions to slow down the reaction
B. Decreasing pressure
lowering the pressure causes the volume to grow so that the collision between the particles decreases, so the reaction takes place more slowly
C. Decreasing temperature
lowering the temperature makes the reaction rate run slower, because temperature is related to kinetic energy, heating makes kinetic energy increase and particle collisions occur more often because particles move faster
So the correct answer is A. add a positive catalyst
the rate of a reaction
the rate of a reaction can be increased
Endothermic and exothermic reactions
the rate of a reaction can be increased2
