AIM: To plan an experiment to investigate the effect of concentration on the initial rate of reaction between Calcium Carbonate and Hydrochloric Acid. Carbonate + Acid --> Chemical Salt + Water + Carbon Dioxide Calcium Carbonate + Hydrochloric Acid --> Calcium Chloride + Water + Carbon Dioxide CaCO3(s) + 2HCl(aq) --> CaCl2(aq) + H2O(l) + CO2(g) reactants products Rate of reaction is how much reactant (i.e. marble chips) is converted to product per unit of time. We can't work out the rate of reaction from a chemical equation. Equations can only tell us how much product we can get. They don't say how quickly it is made. We can only find the rate by actually doing experiments. During a reaction we can measure how much reactant is used up in a certain time. On the other hand, we can also measure how much product is formed in a certain time. In order to investigate this I...
