Daniel Leigh 11Saul Chemistry Course Work A student investigated the reaction between an acid and magnesium metal. He wanted to discover if the concentration of the acid had any effect upon the rate of reaction. The apparatus used: * a graduated tube * a delivery tube * dilute acid * trough * water * Magnesium ribbons Prediction I predict that the higher the concentration of acid, the faster the reaction because increasing the concentration of reactants in the solution increases the rate of reaction(s). Linking prediction to theory Reaction rate and concentration: The collision theory describes how the rate of reaction increases (the time taken for the magnesium ribbon to disappear when it reacts with the acid) when the concentration of acid increases. As the reaction continues, the concentration of the reacting substances decreases and so does the rate of reaction. The reaction is speeded up if the number of collisions is increased. The higher the concentration of acid used the less time it takes...
