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 gradientof the line is equal to the rate of reaction: 1. the steeper the line, the greater the rate of reaction 2. fast reactions - seen when the line becomes … See more For a chemical reaction to happen: 1. reactant particlesmust collide with each other 2. the particles must have enough energy for them to react A collision that produces a reaction is called a successful collision.
