Rate constant (k)

Definition

The rate constant (k) is a proportionality constant that relates the rate of a chemical reaction with respect to its reactants' concentrations. It determines how quickly or slowly a reaction proceeds.

Activation Energy:

Activation energy is the minimum amount of energy required for particles to undergo effective collisions and initiate a chemical reaction.

Order of Reaction:

The order of reaction refers to how each concentration term in the rate equation affects the overall rate of the reaction.

Temperature Dependence:

The rate constant (k) is typically temperature-dependent. As temperature increases, the rate constant generally increases as well.
