Once I had done the graph I realised that I had a few results were anolomisys. The shape of my graph was going up fast at first then it slowed down. Here are a few points about rates of reaction: Rates of reaction I will be comparing rates of reaction for1 minuet on my graph. The 1 minuet I will be comparing will be from 4mins -5mins. 4 Mins 39/240= 0.1625 CM3/s 4Mins20Secs 43/260= 0.1653846 Cm3/s 4Mins40Secs 47/280= 0.1678571 Cm3/s Evaluation I think my method was a suitable one although I think I could have added more Marble chips to make the rate of reaction a littl...
