WebReaction Rate, Activation Energy, and Temperature The rate constant is directly proportional to temperature and inversely proportion to the activation energy: k = A Because the rate constant is directly proportional to the reaction rate, the relationship between rate, activation energy, and temperature can be summarized as follows: WebThe rate at which the reactant ‘a’ is disappearing is proportional to its concentration at any instance, i.e. Rateα (a - x) Rate = k (a - x) where k = rate constant The concept of rate of reaction is very important to determining chemical reacting systems. WebThe net rate of formation of any species is equal to its rate of formation in the forward reaction plus its rate of formation in the reverse reaction: rate net = rate forward + rate reverse. At equilibrium, rate net 0 and the rate law must reduce to an equation that is thermodynamically consistent with the equilibrium constant for the reaction. fitbit charge 3 vs charge 4 vs charge 5
