Graph setup , and conclusion?

Question

I have completed an experiment which was " to investigate the effect of surface area on the rate of reaction on 'tum' tables and hydrochloric acid" i now have to draw a graph to show my average results and write up my conclusion.

I used these 3 surface areas for the tum tablets : 1 whole table, 2 halves of 1 tablet (cut the tablet in half) , and 1 whole tablet powdered. Now the results were spread by alot , for example my average for 1whole table was 269 secs and average for 2 halves was 239 and my average for powder was 96s. how am i suppose to draw a graph for this??

also for conclusion do i just write " As the surface area increased the rate of reaction also increased " since when doing the concentration test i can just write " As the concentration increased the rate of reaction also increased"
or do i need to state the powder form was the largest and fastest?

Thanks.

Answer 1

" As the surface area increased the rate of reaction also increased "

Yes you do.
