Rates of Reaction


 Starting with the experiment and working out the individual rates of each reaction using the reaction of Sodium Thiosulfate and Hydrochloric acid in a @pascoscientific colourimeter, the students then plotted the rates against concentration and were pleased to get a relationship.

By pooling the class results, they got a set of error bars that showed the experiment could either be a curve 2nd order or a straight line first order.
