Chemistry Help needed!:-(
Naruto:
yeah exactly mostly the wording is smooth line graph...so how can we decide wat to do
like in may/june 2000 it was smooth line graph and i made it a straight line
so this is really confusing...wat to do :-\
Naruto:
Well i dont think it can be either because in the markscheme it is always mentioned wat type of graph should be drawn
Zain-Xa:
in may june 2000 its a curve no ruler i think if they mention smooth it means u dnt have to use a ruler as mentioned in may june 2001 q 5 it only says draw a graph of these results so i used a ruler whereas in q3 they mentioned smooth line......
Zain-Xa:
In chemistry, when plotting a graph of reaction rate, you must draw a curve of best fit through your prints. Lines drawn with a ruler from point to point will not get a mark
this is frm the examiners tips for chem ..... its there in the topic revision checklist
godfather93:
basically when the question has something to do with reaction rate (for example a graph showing the volume of oxygen collected over time taken), the graph will be a curve because every reaction starts, continues for a while, slows down and then stops. a straight line is drawn either for scatter graphs (definitely) or for some line graphs (where time is not one of the variables).
