Hydrochloric acid concentration affecting the reaction rate

Asked by blossom24 | Feb 18, 2008 | GCSE Level > Chemistry > Coursework
blossom24 asks:

I am doing a science coursework investigating hw concentration of hydrochloric acid affects the rate of reaction between hydrochloric acid itself and sodium thiosulphate. I do OCR 21st century additional science and the mark scheme says that to get high marks for my interpretation, my line graph (reaction time and concentration in molar) should have an equation. I can find an equation but what do I do with it? Please help! Also, I have dome my coursework and I want to upload it but does this mean that everyone can see it? Thanks

etutor answers:
I think what they mean here is an equation for the slope of the line, to indicate reaction rate.If you upload your coursework, other people will not see it, only the tutors. Questions are seen, but not work.
