When is the change in mass of a reactant useful?
The change in mass of a reactant or product can be followed during a reaction. This method is useful when carbon dioxide is a product which leaves the reaction container.

How to calculate the rate of a reaction?
The rate of reaction can be analysed by plotting a graph of mass or volume of product formed against time. The graph shows this for two reactions. The steeper the line, the greater the rate of reaction. Faster reactions - where the line becomes horizontal - finish sooner than slower reactions
How is activation energy different for different reactions?
The activation energy is the minimum amount of energy needed for a collision to be successful. It is different for different reactions. 1. Two pairs of particles move towards each other 2. The pairs collide and reform so that each member of the original pair joins with a member of the other pair, forming two new pairs
