Last week we tried a straightforward chemical reaction to investigate alka seltzer reacting v water. We’ve additionally observed the reaction in between baking soda and vinegar before, both of which are an extremely safe for also young children to observe.

You are watching: How to speed up a reaction

Taking this a step further we’re going to investigate just how to speed up a chemistry reaction, when still keeping things very an easy and straightforward to understand.

The nature the the reactants

Reactants room the 2 substances you incorporate to get the reaction. Part react slowly and some lot faster relying on the bond that must be broken. Because that example, yellow is really unreactive, if sodium and also potassium room so reactive the they tarnish instantly once exposed to the air.

Particle Size

The smaller sized the corpuscle the quicker the reaction, this is since there is a bigger surface area obtainable to react with the other substance.

Concentration

The greater the concentration, the much faster the reaction, this is since there is much more of the reactive substance available to react. We’ve observed this really simply in the previous by adding an ext alka seltzer come a lava lamp which offers a bigger and also faster reaction.

Temperature

The higher the temperature the quicker the reaction, this is due to the fact that if you warm up a problem the corpuscle have an ext energy and move about faster definition they have an ext contact with the various other reactive substance.

We’ve designed a very simple experiment to demonstrate this using alka seltzer and also hot and cold water.

Please be mindful when do the efforts this at residence that the water you use isn’t too warm as it can spill the end or to explode the balloon, especially if you usage a smaller container.

How to rate up a chemistry reaction

Can girlfriend guess which of these four jars contained the warmest water?

Catalysts

A Catalyst is a problem that accelerates a chemical reaction yet is not readjusted itself by the reaction and can be used again. Instances of catalysts incorporate platinium which is used in car exhausts to break down harmful emissions and also yeast is a biological catalyst that speeds up the procedure of fermentation.

The opposite result is prove by food in a fridge, the cooler temperature slows under the reaction between oxygen and also bacteria that makes the food spoil. Keeping your food fresher for longer.
