An investigation into how the concentration of hydrochloric acid affects the rate of reaction with marble (calcium carbonate) chips Aim: I wish to investigate the concentration of hydrochloric acid which produces the most carbon dioxide in the quickest time. Factors which affect the rate of reaction: * Temperature- When the temperature is increased, the particles gain kinetic energy and move around faster. This gives them an increased chance of colliding with one another, and so speeds up the reaction. * Concentration of Hydrochloric acid- If the concentration is increased, there will be more particles of acid to collide, and so an increased chance of collision with the calcium carbonate. Because they collide more, the rate of the reaction is increased. * Surface area of marble- If you increase the surface area, the rate if the reaction is increased because more solution can come into contact and collide with the marble at one time. * Using a catalyst-...
