research issues

[Clarissa]

Okay so my project question is- How does temperature affect the speed of a chemical reaction?

So during my background research planning I came up with this- Keywords-Temperature, Speed, Chemical Reaction, Solvent, Water

This keywords helped me make these questions- How will the amount of water affect the results?
How does the concentration of the reactants affect the speed of a chemical reaction?
What will the results be if they were more solvents?

So with these questions i think my topic of research should be CHEMICAL REACTIONS.
I think it should be CHEMICAL REACTIONS but i am not sure please help me, and tell me if i am on track with my reasearch, and please inform me ASAP!!!!

It is unclear to me why at this stage of your project that you need to identify a "topic of research". "CHEMICAL REACTIONS" is a very very broad topic and will provide a huge amount of very diverse articles.

If your project question is "How does temperature affect the speed of a chemical reaction?", then it is far more focused than the broader "CHEMICAL REACTIONS".

"speed of chemical reaction" is more often called "chemical reaction rate".

I suspect your topic of research is at least further refined to be something like "Temperature affects on chemical reaction rates" which is still a fairly broad area.

Chemical reactions can be classified thermally in three categories:
Endothermic - meaning they require or absorb thermal energy from their environment effectively cooling their environment.
Exothermic - meaning they release thermal energy and heat up their environment.
neutral - meaning the net result is no easily measured change in temperature as a result of the chemical reaction.

I suspect that it will be easy to observe experimentally how the reaction rate of endothermic and neutral reactions is affected by the starting temperature.
I suspect that With exothermic reactions, it will be much harder to obtain accurate experimental measurements to in such a way that the starting temperature is the only factor affecting the measurable reaction rate.

Okay so with help my research topic will be on "HOW TEMPERATURE AFFECTS ON CHEMICAL REACTION RATES".


Will that be good enough?

"HOW TEMPERATURE AFFECTS CHEMICAL REACTION RATES" is a much better starting topic. It is still rather broad as there are lots of chemical reactions and temperature can affect different types of chemical reactions differently.

In order to narrow it down further, you are going to have to do some research and figure out what checmical reactions you are interested in experimenting with.

You have another fundamental problem in experimental design if you are trying to answer multiple different questions:
1) How does temperature affect checmical reactions, and
2) How does the amount of water affect the results, and
3) How does the concentration of reactants affect the speed of chemical reaction, and
4) Since you haven't chosen a specific reaction to investigate yet, how do all of the above affect different chemical reactions?

That is going to require lots of different experiments. It is much easier to get an un-ambiguous result from a set of experiments if you are only investigating ONE question specific to ONE factor and keep all of the other factors constant.

Hello. If you are still looking for a specific topic you can find a specific chemical reaction, and then examine the effect of temperature on that specific reaction. Something like "the effect of temperature on the rate of decomposition of an eggplant", or any reaction that interests you.
