PROBLEM A manufacturer wants to start making carbon dioxide on a commercial basis by reacting marble chips with hydrochloric acid. He wants to find out; 1. What factors will affect the rate of this reaction 2. How much carbon dioxide he will obtain when 400 tonnes of calcium carbonate is reacted in an excess of hydrochloric acid. INTRODUCTION/AIM The aim of this investigation is to see how much carbon dioxide can be measured depending on the size of marble chips used. When combined with hydrochloric acid, Carbon dioxide gas is given off, and in this investigation I am measuring rates of reaction. PRELIMINARY INVESTIGATION The rate of reaction depends on how often and how hard the reacting particles collide with each other. Particles have to collide in order to react, and the have to collide hard enough as well. This is called the collision theory. When the temperature is increased the particles all move quicker. If...
