A Guide to Rate of Reactions
... Chemical equilibrium is based on thermodynamics and answers the question: ‘How far does the reaction go?’ Learners are inclined to confuse the two concepts. In this series we explain what we mean by the rate of a reaction and the factors that determine this rate. Whereas this can be very theoretical ...
