Hello I desperately need some help/guidiance, if anyone has done this experiment your help would be highly valued! Basically I had to react Zinc with Sulfuric Acid(@3 different concentrations)...which goes on to produce Zinc Sulfate and Hydrogen. I then added Copper Sulfate(@3 different concentrations) to see how this catalysed the reaction, after doing this I drew initial rate against concentrations for the experiments with the Sulfuric acid and Copper Sulfate. However I need to calculate rates to find k (constant) I can do this but I do not know what to talk about and how this is related to the arrhenius equation, Im a tad confused and hope somebody could fill me in!
