Aim Our aim is to investigate whether changing the molar of hydrochloric acid affects the rate of reaction when it is added to calcium carbonate chips. Prediction/ Hypothesis I predict that the higher the molar of acid the faster the rate of reaction will be with the marble chips. This is because with a higher molar of acid there will be more acid particles to collide with the calcium carbonate, therefore causing a reaction in a faster time. With a lower molar of acid there will be more water molecules, resulting in the less chance of collisions with the calcium carbonate. In the graph there should be a gentle curve in the line of best fit as the molar decreases. Independent variable This will be the variable that I am changing in the experiment. The easiest variable to change and the one probable to give the most accurate results is changing the molar of the hydrochloric...
