- Heat it up to speed it up: increasing temperature. …
- The opposite of social distancing: increasing concentration or pressure to increase reaction speed. …
- Divide and conquer: decreasing particle size to increase reaction speed. …
- Pro gamer move: dropping a catalyst.
How can you speed up reaction?
Add a catalyst
(A substance that reduces activation energy, speeding up the reaction) Increase the concentration of reactants. Increase the concentration of catalysts. Increasing the surface area of reactants (If it’s a solid, try crushing it)
What are 4 factors that can increase the speed of a reaction?
Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst
are the four main factors that affect reaction rate.
How do you speed up an Alka Seltzer reaction?
When seltzer tablets are placed in water, a chemical reaction takes place. The chemical reaction that results will take place faster in
hot water
than in cold water because temperature increases the rate of the reaction.
What are 3 ways to speed up a reaction?
- Increase concentration. This increases the number of collisions. The more collisions per second, the faster the reaction.
- Increase temperature. This increases the number of collisions because the molecules are moving faster. …
- Use a catalyst. A catalyst lowers the barrier to the reaction.
Which reaction is faster Why?
Explanation:
Reactions in phases that easily mix, such as gases and liquids, occur much faster than reactions between solids
. The extent of mixing of the reactants influences the frequency of molecular collisions – if reactants are more thoroughly mixed, the molecules will collide more often and thus react faster..
How can I improve my reflexes?
- Pick a sport, any sport – and practise. What exactly do you want to improve your reflexes for? …
- Chill out. …
- Eat a lot of spinach and eggs. …
- Play more video games (no, really) …
- Use your loose change. …
- Playing ball. …
- Make sure you get enough sleep.
What slows down a reaction?
To slow down a reaction, you need to do the opposite. Factors that can affect rates of reactions include surface area, temperature, concentration, and the presence of
catalysts and inhibitors
. Temperature – Changing the temperature of a chemical reaction also affects the reaction rate.
What is the fastest reaction time?
The fastest possible conscious human reactions are
around 0.15 s
, but most are around 0.2 s. Unconscious, or reflex, actions are much faster, around 0.08 s because the signal doesn’t have to go via the brain.
How do you know if a reaction is slow or fast?
The overall reaction rate depends almost entirely on
the rate of the slowest step
. If the first step is the slowest, and the entire reaction must wait for it, then it is the rate-determining step.
What are the 5 factors that affect reaction rate?
Five factors typically affecting the rates of chemical reactions will be explored in this section:
the chemical nature of the reacting substances
, the state of subdivision (one large lump versus many small particles) of the reactants, the temperature of the reactants, the concentration of the reactants, and the …
How do Catalysts speed up reactions?
Catalysts make such a breaking and rebuilding happen more efficiently. They do this by
lowering the activation energy for the chemical reaction
. Activation energy is the amount of energy needed to allow the chemical reaction to occur. The catalyst just changes the path to the new chemical partnership.
What makes Alka-Seltzer dissolve faster?
The Alka-Seltzer tablet dissolved the quickest in the
water
because water is the liquid that the Alka-Seltzer tablet was designed to dissolve in. Also, Alka-Seltzer tablets dissolve quicker in larger amounts of liquid compared to smaller amounts of liquid.
How long does it take for Alka-Seltzer to leave your body?
It stays in your system for
up to 46 hours
, but its effect on platelets lasts longer. This is not a blood thinner. The best four to six!
Why does Alka-Seltzer work so well?
01 INTRODUCTION. When too much acid builds up in your stomach, you can get heartburn. Alka-Seltzer is a “buffer” which
neutralizes stomach acid
and temporarily keeps it from becoming too acidic.
Which is faster sn1 or SN2?
SN2
will be faster if: 1.. Reagent is a strong base. … SN2 reactions need space to inter into the molecule and to push the leaving group that’s why the molecule must not be bulky.
