Core practical 7. As A is to the power 1 we can just write [A]. When was the last time, if ever, the average student has come across marble chips in everyday life? This practical activity is helpful in developing an understanding of the effect of particle size on surface area. In this case we can write m as zero and say that the order with respect to A is zero. This needs to be done manually if they are to develop the skill of determining initial rate by drawing tangents to the line see Developing maths skills below. This enables the collection of data and allows students to demonstrate a quantitative as well as a qualitative approach to this practical activity.

    After a few minutes the bubbles of gas form less and less quickly until finally no bubbles appear because all the acid has been used up, some zinc remains. There are many experiments you can use and some of these were discussed in an earlier article.

    The study of rates is fundamental to a student's understanding of chemical reactions. Students encounter the idea that reactions are the result of.

    In practice these means that as you increase the concentration of A, the rate of reaction will increase by the same proportion, for example if you double the amount of A, the rate would double as well.

    So the rate of reaction is effectively the speed the product is formed and also the speed with which the reactant is used up.
