James Curry 10X1 AT1 Assessed Practical What is the effect of the concentration of hydrochloric acid on the rate of reaction, in a reaction between hydrochloric acid and marble chips? I will attempt to find out what the relationship is between the rate of the reaction and the concentration by conducting a series of experiments in which I will react marble chips with hydrochloric acid and observe the reaction and it's results. I will measure the amount of hydrogen given off in the reaction every 10 seconds over a set period of 100 seconds. With this data, gas given off/time, I can create graphs, analyse them and, from this analysis, draw a conclusion. All the variables must be closely controlled in order to make this experiment fair. The evidence must be read and recorded carefully and precisely so that it can be processed accurately and used to justify the prediction below. Variables The variables that...
