Pritesh Mistry 10H 20/5/01 Chemistry Coursework: Investigating the effect of Concentration on the Rate of Reaction In the investigation that I am going to do I am going to try and find out how the rate of reaction is affected by different concentrations of acid, ranging from 1M to 2.5M. Variables The variables in this experiment will be the concentration of the acid. The surface area of the marble chips could also be a variable, but not to such an extent because this is only variable as there is no accurate way in measuring the surface area of the marble chips. In this case the key variable being the concentration of the acid. The elements that will be kept constant will be temperature (kept at room temperature), the size and weight of the marble chips, the volume of acid, and the time intervals at which the results will be recorded (10...
