Chemistry, the effects of acid rain includes experiment with marble chips.

Chemistry coursework on acid rain I predict that as the temperature is increased the rate of reaction will increase. I also predict that as the concentration of the sodium thiosulphate increases the rate of reaction will increase. This means that both graphs drawn up in my analysis will have positive correlation, and will probably be curved, as the increase in rate of reaction will not be exactly the same as the concentrationtemperature is increased. This …

…than the activation energy. Increasing the surface area increases the chance of the particles hitting the reactant (colliding) and allows more particles to react with the reactant all at once. The bigger the surface area of Calcium Carbonate, the greater the number of collisions, Carbon Dioxide was given off at a quicker rate. Therefore the rate of the reaction slowed down as the size of the particles was increased from powder to 9-12mm pieces
