Reaction Rates

Reaction Rates. Different reactions take place at different rates. Spontaneous vs. Non-spontaneous (reactants vs. products) Nature tends towards stability. Reaction Rates. Thermodynamically stable: a reaction which has an overall positive energy change (non-spontaneous, endothermic).
