Does the concentration of acid affect the rate of reaction? Chemical reactions can take place at different speeds. A reaction, which is over in a fraction of a second, is a very fast reaction. (It has a high rate of reaction.) As the time taken for the reaction to be completed increases, the rate of reaction decreases, and as the speed for the reaction to be completed decreases the rate of reaction increases. Rate of reaction = 1/time The effect of increasing concentration on the rate of reaction is easy to predict qualitatively from the experiment between magnesium ribbon and hydrochloric acid. In the diagram below it can be seen that increasing the concentration of acid from one mole per dm3 to two moles per dm3, while keeping all the other variables the same causes more bubbles of hydrogen to be formed. I.E increases the rate of reaction. To find out all of...
