Chem Student Experiment: Rationale

[jinx_58]

Hello.

I don't know what theory to talk about in my rationale. I think we need to write about collision theory, but I don't to what extent we need to write about.

My experiment is changing the concentration of hydrochloric acid (0.5M, 1M and 2M) and how this affects the reaction rate of the reaction between hydrochloric acid and sodium thiosulphate.

Cheers

In uni chem and VCE chem (not sure what's required of you QCE people so please follow your teacher’s definition), the introduction which is sometimes known as the rationale addresses why you’re conducting your experiment, has this or a similar experiment been conducted before (quoting some references on collision theory), what are some practical, real world applications you’d expect from the results you obtain (maybe the implications for water safety, if there’s a higher concentration of a particular carcinogen in drinking water, its effects are more severe than lower concentrations due to there being more particles colliding with your DNA and mutating them in some way), as well as your aim and hypothesis.

Okay, thank you
