We are investigating 'how the rate of a catalysed chemical reaction is affected by a catalyst', need some advice on part c of the conclusions

Heya, I'm going to put this in the Chemistry forum for you as you should get more responses there.

You should also check out the forum to see if there's any other threads there which might be helpful to you! http://www.thestudentroom.co.uk/forumdisplay.php?f=130

This is too vague without knowing your results!

What did you find?

We used a catalyst of manganese dioxide to be used with the reactant hydrogen peroxide to decompose into oxygen and water, we used a range of manganese dioxide masses of 0.1-0.5.
The results where that the time taken to give oxygen decreases as we increases the catalyst

What relationship does the time taken have to the rate?

How does changing the mass of catalyst change the rate?

What is your fundamental conclusion.
