Chapter 1 Rate of Reaction
Specification learning objectives:
· Explain and use the term rate of reaction
· Deduce the rate of reaction from a concentration-time graph
Rate of reaction depends upon collisions between particles. Collisions must have more energy than the activation energy of the reaction to take place. The number of collisions with energy greater than Ea can be changed by altering the temperature, pressure or in the presence of a catalyst.
Rate of Reaction
The rate of a chemical reaction measures:
· How fast the reactants are used up
· How fast the products are produced
Rate of reaction is usually measured as the change in concentration of a reaction or product per unit time.
Sometimes it is more convenient to use a different physical quantity…
