How does the concentration of hydrochloric acid affect the rate of reaction with calcium chloride? Joe Forster Task: How does the concentration of hydrochloric acid affect the rate of reaction with calcium chloride? Prediction I predict that the higher the concentration the faster the reaction will take place this is because in a higher concentration there will more hydrochloric acid molecules per set volume. This means that there will be a higher chance of the calcium carbonate molecules colliding with the hydrochloric acid and reacting. This should in theory increase the rate of reaction as the concentration is increased. The reaction rate, however, should decrease as the experiment progresses because as the reaction time increases the number of hydrochloric acid molecules present will decrease as they have been reacted. This should decrease the rate of reaction because of decrease in concentration. This should make a graph of the reaction curved as...
